In Brief: On this site you will find pictures and information about some of the electronic, electrical and electrotechnical Obsolete technology relics that the Frank Sharp Private museum has accumulated over the years .
Premise: There are lots of vintage electrical and electronic items that have not survived well or even completely disappeared and forgotten.

Or are not being collected nowadays in proportion to their significance or prevalence in their heyday, this is bad and the main part of the death land. The heavy, ugly sarcophagus; models with few endearing qualities, devices that have some over-riding disadvantage to ownership such as heavy weight,toxicity or inflated value when dismantled, tend to be under-represented by all but the most comprehensive collections and museums. They get relegated to the bottom of the wants list, derided as 'more trouble than they are worth', or just forgotten entirely. As a result, I started to notice gaps in the current representation of the history of electronic and electrical technology to the interested member of the public.

Following this idea around a bit, convinced me that a collection of the peculiar alone could not hope to survive on its own merits, but a museum that gave equal display space to the popular and the unpopular, would bring things to the attention of the average person that he has previously passed by or been shielded from. It's a matter of culture. From this, the Obsolete Technology Tellye Web Museum concept developed and all my other things too. It's an open platform for all electrical Electronic TV technology to have its few, but NOT last, moments of fame in a working, hand-on environment. We'll never own Colossus or Faraday's first transformer, but I can show things that you can't see at the Science Museum, and let you play with things that the Smithsonian can't allow people to touch, because my remit is different.

There was a society once that was the polar opposite of our disposable, junk society. A whole nation was built on the idea of placing quality before quantity in all things. The goal was not “more and newer,” but “better and higher" .This attitude was reflected not only in the manufacturing of material goods, but also in the realms of art and architecture, as well as in the social fabric of everyday life. The goal was for each new cohort of children to stand on a higher level than the preceding cohort: they were to be healthier, stronger, more intelligent, and more vibrant in every way.

The society that prioritized human, social and material quality is a Winner. Truly, it is the high point of all Western civilization. Consequently, its defeat meant the defeat of civilization itself.

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

OLD, but ORIGINAL, Well made, Funny, Not remotely controlled............. and not Made in CHINA.

GOODWILL GW503 5.5 PERSONAL BLACK & WHITE TV AM/FM RADIO CHASSIS 501C-TV + TV501A-R INTERNAL VIEW.




The chassis is a little center placed PCB with all part on it.
  The whole board is built around the CD5151CP. Excluding passives this chip seems to have everything needed to build a TV receiver : video and audio intermediary frequency, tuner frequency control, automatic gain control, FM detector for audio, detection of synchronization pulses and horizontal and vertical deflection oscillators and drivers. There is also a TA8164P, which is a radio tuner IC. The CD5151CP already has integrated FM decoding circuitry. It may have something to do with the SECAM-L standard.


CSC5151 - AN5151 TV VIF & SIF & DEFLECTION SYSTEM (FOR TV LARGE INTEGRATION)

DESCRIPTION
The UTC AN5151 is a monolithic integrated circuit containing
all stage for the VIF,SIF and deflection of television receivers.
 GENERALLY, the operation of a conventional television receiver includes two main components. First, the receiver receives the incoming television signal in radio frequency (RF) and converts the incoming RF signal to an intermediate frequency (IF) signal. Then, the receiver converts the IF signal to a video baseband signal and an audio baseband signal. The baseband signals are coupled to appropriate video and audio decoders to generate the display video signals (e.g. RGB or only luminance for b/w) or sound. In general, the conventional television receiver includes a tuner for receiving the input RF signal and converting the RF signal to an IF signal by one or more frequency conversions. The frequency conversions are generally implemented as single or dual super-heterodyne conversions. In conventional television receivers, the intermediate frequency is dictated by the geographical area the receivers are to be used.
FEATURES
*Hight integrated technology makes it possible the integration of
video IF circuit tuner AFC circuit sound. IF circuit and
deflection.-jungle circuit on one single chip.
*supply voltage range:8V to 12V

Also, the conventional television receiver also includes a channel filter and a demodulator for converting the IF signal to video and audio baseband signals. The channel filter is typically a discrete filter implemented as a SAW (Surface Acoustic Wave) filter see pictures. The shape of the SAW filter is designed specifically for the format (analog or digital TV) and the television standard (NTSC, PAL or SECAM) of the television signals being received. The demodulator is typically a dedicated component and designed specifically for a predetermined television signal format and a predetermined television standard. For analog television signal reception, the demodulator is a VIF/SIF module. The VIF/SIF module provides a video output called CVBS (Composite Video Baseband Signal) and audio outputs, such as MPX or A2.

FUNCTIONS
*IF Amplifier, IF AGC
*Video Amplifier, Video Detector
*Noise Canceller, Forward RF AGC
*Tuner AFT,SIF Amplifier
*Sound Detector, sync separation
*Vertical oscillation trigger and driver
*Horizontal oscillation driver and AFC




The circuit here shown is an extreme example of semplification of a b/w tv receiver in accordance of above statements.

TA8164P 3V MONAURAL RADIO IC
The TA8164P is AM/FM Tuner (FM F/E + AM/FM IF) IC, which is designed for AM/FM monaural radio. Combining with the TA7368P (Mono PW IC), a suitable monaural AM/FM radio system is able to be constituted.
FEATURES

GOODWILL GW503 5.5 PERSONAL BLACK & WHITE TV AM/FM RADIO CHASSIS 501C-TV + TV501A-R CRT TUBE HAI-SHI 14SX5Y4

 


Chungwha Picture Tubes, Ltd. (CPT) is one of Taiwan's, and the world' s, leading manufacturers of thin-film transistor liquid crystal displ ays, or TFT-LCDs. Ranked number three in the Taiwan TFT panel market, the company is also a leading producer of cathode ray tubes (CRTs), color picture tubes, and electron guns used for CRT-based monitors an d televisions. While those markets represent the group's traditional business, CPT responded quickly to the rise of flat-panel technologie s at the dawn of the 21st century, embracing both LCD and plasma-base d technologies. The company has manufacturing operations in Taiwan (i ncluding a 6G plant expected to reach full production by the end of 2 005) and in mainland China and Malaysia. Listed on the Taiwan Stock E xchange, CPT was founded by Taiwan's Tatung Corporation, which remain s its major shareholder with more than 32 percent of the company's st ock. The bruising competition with Japanese and especially Korean fla t-panel producers has left CPT, like most of the Taiwanese flat-panel sector, struggling to keep up and maintain profitability. As a resul t, CPT has long been rumored to be seeking a merger with a fellow Tai wanese LCD producer in order to gain greater scale. In 2004, CPT post ed sales of TWD 117 billion ($3.67 billion).

Tatung Offshoot in the 1970s
Chungwha Picture Tubes had its origins as an offshoot of the fast-gro wing Tatung Corporation, one of the motors of Taiwan's industrial dev elopment in the second half of the 20th century. Tatung's roots lay i n the post-World War I period, when Shan-Chih Lin went into business, founding the Shan-Chih Business Association in 1918. Lin's business flourished and by 1939 Lin's interests had grown to include the newly founded Tatung Iron Works. That company became known as Tatung Steel and Machinery Corporation following World War II.
Tatung was to play an important role in the development of the new Ta iwanese state in the 1950s. The company diversified, adding an applia nce manufacturing component. In 1949, Tatung launched production of i ts first appliance, an electric fan. That product soon brought the co mpany to the export market, with its first international sales shippi ng to the Philippines.
By the early 1960s, Tatung had added refrigerators and automatic stea mers to its list of appliances. The company then began construction o f two new factories, one for the production of air conditioners, and another for the manufacture of television sets. This latter category represented Tatung's introduction to the large electronics sector. Pr oduction of televisions began in 1964; the following year, the compan y incorporated a new subsidiary, Tatung Electronics.

By 1968, Tatung had extended its television production expertise to t he production of color televisions. The company also began to explore the potential for broadening its technology, namely for the producti on of the cathode ray tubes at the heart of the television industry. This effort led the company to create a new dedicated subsidiary, Chu ngwha Picture Tubes (CPT), in 1970. Construction of the company's fir st production facility in Taoyuan began in 1971.

CPT initially focused on the black and white tube sector, launching a test production run in 1972. By 1973, the company had perfected its production technique, and began full-scale production. CPT's prior ex port experience enabled it to gain a solid foothold in international markets, shipping CRTs to the Americas and to Europe, as well as to T hailand and other Asian markets. In 1974, as well, CPT added producti on of another important television component, the electron gun. In th at year, the group's tubes received certification by the United State s, giving the company entry into that market as well.
The rise of new graphics-based computers in the late 1970s gave CPT a fresh outlet for its cathode ray tubes. While computer monitors rema ined black and white, the television market had by then largely switc hed over to the color television standard. CPT responded by launching production of its own color CRTs at a new dedicated production facil ity in Taoyuan in 1978. Sales of the new tubes were swift; by the ear ly 1980s, the company had produced more than one million color CRTs.

The Taiwanese government adopted a new policy in the early 1980s of e ncouraging Taiwan's shift away from its position as a low-cost, low-t echnology industrial producer toward a high-technology model. Tatung and CPT responded by expanding their operations to include the fast-g rowing computer sector, and especially the personal computer market. In 1983, CPT sought to extend its own display expertise into a new an d promising display type, a flat-panel display based on liquid crysta ls. Whereas liquid crystals had been discovered in the 19th century, practical applications of the material only appeared toward the end o f the 1960s, when RCA in the United States developed the first liquid crystal displays. By the end of the 1970s, however, Japan had become the focal point for LCD technologies.

Chungwha became the first Taiwanese company to attempt to enter the L CD market in 1983. Yet CPT proved unable to develop the necessary tec hnology on its own, and the Japanese LCD industry jealously guarded i ts own technology advantage. Instead CPT returned its focus to the CR T market. In 1985, the company succeeded in developing a technology t ransfer partnership with Japan's Toshiba, not for the production of L CDs, but rather for the production of 14-inch color CRTs for computer and other monitor displays. By the end of that year, CPT had begun p roducing medium-resolution 14-inch CRTs as well as related components .
CPT launched its first flat-screen CRT in 1986 based on a 5.5-inch tu be. By the end of that year, the company also ramped up production of a 14-inch flat rectangular CRT. In order to meet rising demand for i ts CRT, the company built a new facility in Yang Mei, started in 1987 and completed in less than a year. That facility began producing 14- inch high-resolution displays, as well as 21-inch flat rectangular CR Ts.

LCD Beginnings in the 1990s
CPT followed Tatung overseas in the early 1990s. While Tatung built a new construction facility in Thailand, CPT turned to Malaysia, where it began building a plant for the production of color electron guns in 1990. The Malaysian subsidiary reached full production by 1991, th en quickly expanded to eight production lines by the middle of the de cade. The addition of the Malaysian production capacity helped CPT cl aim the leading position in the global CRT industry.
The mid-1990s also marked a new effort by CPT to enter the LCD market . In 1994, the company began building a dedicated facility in Fuzhou. In the meantime, the company continued to boost its CRT capacity. A major step in the group's development came with a new technology tran sfer agreement with Toshiba in 1995, enabling CPT to launch productio n of 28-inch and larger color picture tubes. The following year, CPT established a manufacturing presence in the European market, opening a production subsidiary in Scotland.
Yet the future of the display industry lay in the fast-developing LCD technology. CPT's efforts paid off by 1996 with the production of th e group's first LCD module. By 1996, the company's factory prepared t o launch full-scale production.

CPT's efforts to crack the LCD sector were aided by the economic down turn in Japan. Into the late 1990s, that country's LCD giants began t o find it difficult to raise the funds needed for further investment. These companies risked falling behind in the newly launched LCD race , as new competitors, especially in Korea, emerged. Meanwhile, the LC D industry was set to take off, as more and more users adopted portab le computers, but especially as the world prepared for the sudden exp losion in portable telephones. Slightly further down the road lay the promise of new high-definition television standards, which would req uire consumers to upgrade their sets, and the coming of the flat-scre en televisions as well.
In search of funding, the Japanese LCD makers turned to Taiwan for in vestment capital, launching a series of technology transfer agreement s with the island's manufacturers. CPT proved to be among the first t o find a partner, signing an agreement with Mitsubishi in 1997. By 19 99, the company had completed its new production facility and it beca me the first in Taiwan to produce 14-inch and 15-inch LCD modules.

Display Leader in the 2000s 
CPT's LCD production gained quickly, and by 2001, the company had add ed a second factory, in Fu Chou. The following year, the company adde d two more production facilities, in Wujiang, in mainland China, and in Lungtan. The company continued to produce CRTs, but the future cle arly lay in flat-panel technologies.
In the early 2000s, CPT began developing production capacity for plas ma screens as well. By 2001, the company had successfully launched pr oduction of display panels ranging up to 46 inches in size. The compa ny continued to develop its technology, and by 2004, CPT debuted its first high-definition large-screen panels.
As for its Taiwanese counterparts, including AU Optronics and Chi Mei Optoelectronics, the early 2000s proved a difficult period for CPT. The economic downturn had suppressed sales; at the same time, the com pany faced heavy competitive pressure from its deep-pocketed rivals i n South Korea. The result was a swift drop in the prices of LCD and f lat-panel displays. Although this stimulated massive consumer demand for these display types, the falling prices sent most of the Taiwanes e sector into losses. In order to compete, CPT, like the other Taiwan ese display leaders, was forced to invest heavily in expanding its pr oduction, building new fifth-generation plants. By 2005, the company had also committed to expanding production with a new sixth-generatio n plant, to be completed by the end of that year.

Continued losses (CPT's losses topped $226 million for the first half of 2005 alone) made it difficult for CPT to raise needed investm ent capital. At the same time, Tatung was said to be seeking to offlo ad its money-losing subsidiary, which had been dragging down its own profits. Into the mid-2000s, rumors began to circulate that Tatung wa s preparing to merge CPT with one of its rivals. By September 2005, t he rumor, although denied by Tatung, appeared to become more of a cer tainty. At that time, two likely candidates emerged. The first was Ho n Hai-owned Innolux Display Corp., the current number six in Taiwan. The second was Quanta Display Inc., the market's number five, part of the Quanta Group. The merger with either of these candidates was exp ected to boost CPT, the market's number three, into the industry's nu mber two position, ahead of Chi Mei Optoelectronics, and trailing onl y AU Optronics. CPT remained a key player in Taiwan's effort to lead the global flat-panel display market.

SONY KV-M14A YEAR 1989.

 

The SONY KV-M14A is A Portable television monitor type SONY TRINTRON with 14 Inches color screen .It has full OSD and others features like a VST tuning system.VST Tuning more specifically, the present relates to a tuning voltage generating apparatus of a voltage synthesizer type for supplying a tuning voltage to a tuner employing a variable reactance element as a tuning element.
 It is customary to perform the tuning operations in TV receivers while a viewer manually rotates a tuning knob. However, the tuning operation is bothersome particularly in case of the continuously varying tuning operation such as in UHF reception. Though tuning operation is considerably simpler in case of TV receivers of the recently developed touch control type or remote control type, it is difficult for a non-skilled person the to preset tuning operation, namely, to adjust the tuning frequencies for respective broadcasting stations before starting to watch a TV receiver. The set features an automatic tuning scheme for use in TV receivers which includes a start/stop circuit which creates a search start signal and a search stop signal upon the receipt of a search start instruction and a detected incoming signal, respectively, a tuning voltage generator which generates a gradually varying tuning voltage under control of the search start signal and search stop signal, and a memory circuit for storing the tuning voltage from the generator when desired. The tuning voltage stored in the memory circuit is supplied to a tuner including a well known voltage-sensitive capacitance diode.
 
A Scart socket is also present toghether with RCA inputs backside placed..

The speaker is located above the cabinet.


The television receiver has an alphanumeric display which appears on the picture tube screen, to give the user data on the tuned channel number, colour settings and other operating data. The digital processor which generates the characters for display also controls the channel setting, etc., under the control of a digital remote control unit . The processor has an associated memory circuit for permanent tuning back up.On screen display (OSD) arrangements employed in video processing systems include a switching (or "multiplexing") network for switching between graphic image representative signals and normal video signals so that a graphic image can be displayed on the screen of a picture reproduction device either in place of the image represented by the video signals or together with (inserted in) the image. The graphic image can take the form of alphanumeric symbols or-pictorial graphics, and can be used to indicate status information, such as channel numbers or time, or operating instructions.
In an OSD arrangement for use in an analog video signal processing system, the multiplexing network typically operates to switch in levels corresponding to the desired intensity of respective portions of the graphic image at the time the graphic image portions are to be displayed. In such an arrangement the graphic image representative signals take the form of timing pulses which occur when the graphic image portions are to be displayed and are used to control the multiplexing network.

The set was first portable SONY equipped with the monocarrier Chassis BE-1 wich integrates all parts of the set except the video section which was featured on a plug in unit !

The pictures produced by this set are powerful, sharp and bright, no surprises if any LCD Toy can't compete with this.

The Trinitron colour tube, designed by and used exclusively by Sony in all its colour receivers, was the first to have an in -line gun arrangement. The Cathode Ray Tube (CRT) has been slowly changing since its con- ception about 50 years ago. Since then the emitter, accelerator and focus structures at the “gun” end have been added to the vacuum tube to shape and control the amount of electrons from the gun. At the target end of the CRT, the luminescent screen is made of a phos- phor mixture. Phosphor glows white when struck by electrons. Phos- phor brightness is directly proportional to the amount of electrons that strike the phosphor. The CRT sport brightness was controllable with a gun and phosphor screen. The electron beam produced a spot of light that was stationary on the phosphor screen. Placing an electromagnetic field near the electron beam after it left the gun created movement. The spot intensity and location were now controllable and the CRT became known as the pic- ture tube. To produce a color picture on the CRT screen; three independent gun structures are used. The electron guns produce different amounts of electrons targeted to their corresponding Red, Green and Blue phos- phors. Red, Green and Blue are the primary colors for light. In 1968 the Sony Trinitron picture tube was a departure from the tradi- tional three-gun color picture tube. Three major changes to the old color tube created a distinctive Trinitron picture tube:
 1. Instead of three small electron guns, focus was improved using one large electron gun structure that all three beams pass through.
 2. Electrostatic convergence plates were added to bend the outer elec- tron beams so they would land on the corresponding red and blue color phosphor.
 3. A continuous vertical slotted aperture grill at the screen end that: • Reduces the effects of terrestrial magnetism. • Prevents adjacent and stray electrons from striking the wrong phos- phor. • Allows more electrons to pass, increasing brightness without short- ening life. • Results in a flat screen. This reduces annoying room light reflections (glare).
It has a single gun assembly with three cathodes mounted in line horizontally, a striped -phosphor screen, an aperture grill with vertical slots instead of the traditional type of shadowmask, and a faceplate with cylindrical rather than parabolic curvature. The Trinitron tube produces a very good display - some people, including the   Obsolete Technology Tellye ! - author, would say the best aven if some exceptions with the PHILIPS ERF Series. There are sound technical reasons for making this claim, for example the design of the large electron lens which provides excellent resolution. An advantage of the cylindrical in comparison with the traditional parabolic faceplate is the fact that most of the external light that falls on it is reflected away from instead of towards the viewer, thus improving the. contrast and reducing eye strain.
The Black Trinitron introduced a couple of years ago gives a further improvement in this respect (the faceplate has been darkened to a black colour). Since the first Trinitron tubes appeared in the UK in the late sixties there has not been a great deal of change in the design, though a number of improvements have been introduced. More recently we have had the Black Trinitron mentioned above and the Pan -focus gun which gives uniform focusing over the entire screen area, eliminating any need for dynamic focusing but further added in large screen models in the 70's and 80's and 90's.


The set has an AV SCART SOCKET.

A SCART Connector (which stands for Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a standard for connecting audio-visual equipment together. The official standard for SCART is CENELEC document number EN 50049-1. SCART is also known as Péritel (especially in France) and Euroconnector but the name SCART will be used exclusively herein. The standard defines a 21-pin connector (herein after a SCART connector) for carrying analog television signals. Various pieces of equipment may be connected by cables having a plug fitting the SCART connectors. Television apparatuses commonly include one or more SCART connectors.
Although a SCART connector is bidirectional, the present invention is concerned with the use of a SCART connector as an input connector for receiving signals into a television apparatus. A SCART connector can receive input television signals either in an RGB format in which the red, green and blue signals are received on Pins 15, 11 and 7, respectively, or alternatively in an S-Video format in which the luminance (Y) and chroma (C) signals are received on Pins 20 and 15. As a result of the common usage of Pin 15 in accordance with the SCART standard, a SCART connector cannot receive input television signals in an RGB format and in an S-Video format at the same time.
Consequently many commercially available television apparatuses include a separate SCART connectors each dedicated to receive input television signals in one of an RGB format and an S-Video format. This limits the functionality of the SCART connectors. In practical terms, the number of SCART connectors which can be provided on a television apparatus is limited by cost and space considerations. However, different users wish the input a wide range of different combinations of formats of television signals, depending on the equipment they personally own and use. However, the provision of SCART connectors dedicated to input television signals in one of an RGB format and an S-Video format limits the overall connectivity of the television apparatus. Furthermore, for many users the different RGB format and S-Video format are confusing. Some users may not understand or may mistake the format of a television signal being supplied on a given cable from a given piece of equipment. This can result in the supply of input television signals of an inappropriate format for the SCART connector concerned.
This kind of connector is todays obsoleted !


Sony Corporation (Sonī Kabushiki Gaisha) (TYO: 6758, NYSE: SNE), or commonly referred to as Sony, is a Japanese multinational conglomerate corporation headquartered in Minato, Tokyo, Japan and the world's fifth largest media conglomerate with revenue exceeding ¥ 7.730.0 trillion, or US$77.20 billion (FY2010).

Sony is one of the leading manufacturers of electronics, products for the consumer and professional markets.

Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its eight operating segments – Consumer Products & Devices (CPD), Networked Products & Services (NPS), B2B & Disc Manufacturing (B2B & Disc), Pictures, Music, Financial Services, Sony Ericsson and All Other. These make Sony one of the most comprehensive entertainment companies in the world. Sony's principal business operations include Sony Corporation (Sony Electronics in the U.S.), Sony Pictures Entertainment, Sony Computer Entertainment, Sony Music Entertainment, Sony Ericsson, and Sony Financial. As a semiconductor maker, Sony is among the Worldwide Top 20 Semiconductor Sales Leaders.

Its founders Akio Morita and Masaru Ibuka derived the name from sonus, the Latin word for sound, and also from the English slang word "sonny", since they considered themselves to be "sonny boys", a loan word into Japanese which in the early 1950s connoted smart and presentable young men.

History
Masaru Ibuka, the co-founder of Sony:

In late 1945, after the end of World War II, Masaru Ibuka started a radio repair shop in a bomb-damaged department store building in Nihonbashi of Tokyo. The next year, he was joined by his colleague, Akio Morita, and they founded a company called Tokyo Tsushin Kogyo K.K., (Tokyo Telecommunications Engineering Corporation). The company built Japan's first tape recorder called the Type-G.

In the early 1950s, Ibuka traveled in the United States and heard about Bell Labs' invention of the transistor.He convinced Bell to license the transistor technology to his Japanese company. While most American companies were researching the transistor for its military applications, Ibuka and Morita looked to apply it to communications. Although the American companies Regency[disambiguation needed] and Texas Instruments built the first transistor radios, it was Ibuka's company that made them commercially successful for the first time.

In August 1955, Tokyo Tsushin Kogyo released the Sony TR-55, Japan's first commercially produced transistor radio.

They followed up in December of the same year by releasing the Sony TR-72, a product that won favor both within Japan and in export markets, including Canada, Australia, the Netherlands and Germany. Featuring six transistors, push-pull output and greatly improved sound quality, the TR-72 continued to be a popular seller into the early sixties.

In May 1956, the company released the TR-6, which featured an innovative slim design and sound quality capable of rivaling portable tube radios. It was for the TR-6 that Sony first contracted "Atchan", a cartoon character created by Fuyuhiko Okabe, to become its advertising character. Now known as "Sony Boy", the character first appeared in a cartoon ad holding a TR-6 to his ear, but went on to represent the company in ads for a variety of products well into the mid-sixties.[8] The following year, 1957, Tokyo Tsushin Kogyo came out with the TR-63 model, then the smallest (112 × 71 × 32 mm) transistor radio in commercial production. It was a worldwide commercial success.

University of Arizona professor Michael Brian Schiffer, Ph.D., says, "Sony was not first, but its transistor radio was the most successful. The TR-63 of 1957 cracked open the U.S. market and launched the new industry of consumer microelectronics." By the mid 1950s, American teens had begun buying portable transistor radios in huge numbers, helping to propel the fledgling industry from an estimated 100,000 units in 1955 to 5,000,000 units by the end of 1968.

Sony's headquarters moved to Minato, Tokyo from Shinagawa, Tokyo around the end of 2006.
Origin of name

When Tokyo Tsushin Kogyo was looking for a romanized name to use to market themselves, they strongly considered using their initials, TTK. The primary reason they did not is that the railway company Tokyo Kyuko was known as TKK.

 The company occasionally used the acronym "Totsuko" in Japan, but during his visit to the United States, Morita discovered that Americans had trouble pronouncing that name. Another early name that was tried out for a while was "Tokyo Teletech" until Morita discovered that there was an American company already using Teletech as a brand name.

The name "Sony" was chosen for the brand as a mix of two words. One was the Latin word Sonus which is the root of "sonic" and "sound" and the other was "sonny," a familiar term used in 1950s America to call a boy.The first Sony-branded product, the TR-55 transistor radio, appeared in 1955 but the company name did not change to Sony until January 1958.

At the time of the change, it was extremely unusual for a Japanese company to use Roman letters to spell its name instead of writing it in kanji. The move was not without opposition: TTK's principal bank at the time, Mitsui, had strong feelings about the name. They pushed for a name such as Sony Electronic Industries, or Sony Teletech. Akio Morita was firm, however, as he did not want the company name tied to any particular industry. Eventually, both Ibuka and Mitsui Bank's chairman gave their approval.

By Japanese standards Sony is a comparative newcomer. It started out in May 1946, recently celebrating its fiftieth anniversary. Most of the major Japanese companies in the consumer electronics field were formed much earlier. Hitachi and Toshiba for example date from the nineteenth century, Matsuhsita from the early years of the twentieth century. During those fifty years however Sony's achievements have been second to none. Sony started operations as Tokyo Tsuchin Kogyo (Tokyo Telecommunications Engineering Corporation). Its aim was "to make unique products", and to "create and introduce technologies that larger companies cannot match". One of its earliest achievements was Japan's first reel-to-reel audio tape recorder, which was launched in 1950. The tape to go with it, also developed by the company, was called Soni-tape. In 1954 the company launched the first all -transistor radio to go into production anywhere. When, in the following year, it decided to start exporting, a simple brand name that would be easily recognised in any part of the globe was required. Sony was the obvious answer, and in 1958 the company changed its name to the Sony Corporation. The Sony Corporation of America was set up in 1960. Sony UK, in 1968, brought Sony to Europe. Innovation continued apace. In 1960 Sony launched the fast fully transistorised portable TV receiver. Five years later the first open -reel video tape recorder for domestic use was introduced. The Trinitron colour system arrived in 1968. It was incredible, though typical, that Sony should develop its own colour TV tube from scratch. While relying on the traditional three primary colour phosphors and a shadowmask, the phosphors were laid down in stripes, the mask became a shadow grille, the guns were arranged in -line and the faceplate became much flatter. This was to be the way tube development would go. The Betamax VCR system was introduced in 1975. It is today generally accepted that it was the best of its time. But, as with the Trinitron system, Sony wouldn't licence it to other manufacturers. That mistake led to its demise, and wasn't repeated. The 8nun video system, which has come to dominate the camcorder field, was launched by Sony ten years later, in 1985. Meanwhile Sony had had an extraordinary success with the Walkman portable audio system, which was launched in 1979. This is claimed to have been "the single best-selling consumer electronics product ever marketed". Sony kept up the pace of development, moving on to digital systems. The MiniDisc, capable of both record and playback, arrived in 1993. In 1995 Sony was first to launch a digital camcorder. A home DV recorder is due later this year, along with a device called the DV cap: this links a DV camera to a PC for editing and image manipulation. There have been a number of other significant developments in recent times. The highly successful PlayStation established Sony in the video games market. Sony is to introduce its first PC later this year, while "a true living -room computer" is promised for next year. Plasmatron large, flat screen TV sets are already available in Japan. DVD players are another imminent prospect. All in all it has been an extraordinary story, and Sony's position at the centre of electronics development looks set to continue indefinitely. The company has combined world -class R&D capabilities, manufacturing excellence, the ability to read and to create markets, and remarkable marketing skills. The UK's main CE innovator for a long time, Amstrad, makes a sorry contrast. For a time Amstrad couldn't do anything wrong. It came up with a string of innovative ideas and products, skillfully meeting and developing user requirements. Packaged audio, wordprocessors then an IBM PC clone. There were the combined TV/VCR units, then the video Double Decker. Amstrad was in and out of audio, video and TV, always with highly competitive products. The company came up with the first Sky package at under £200. But while it came up with products that met contemporary needs, it never seemed to take root and grow. We are now witnessing its final dismemberment. Psion, the hand-held computer manufacturer, is negotiating to take over Amstrad's digital telephone interests, which fit in with its own product development programme. Amstrad's loss - making consumer electronics interests are to be split between Betacom, an affiliated company, and a new company to be called Digicom Technology. The latter will take over Amstrad's analogue satellite business and inherit a small R&D operation. How did Sony succeed, starting out with twenty employees, no machinery and negligible capital, while Amstrad simply shuffles off stage? Because Amstrad never developed a comprehensive business strategy. It came up with bright ideas, subcontracted production, stocked up then walked away as soon as the market turned.

It's the tragic story of much of UK and European industry.
