Reference excerpt

The history of Sony, a Japanese multinational conglomerate, dates back to 1946.

Founding In September 1945, after the end of World War II, Masaru Ibuka started a radio repair shop in the bomb-damaged Shirokiya department store building in the Nihonbashi district of Tokyo. The next year, he was joined by his wartime research colleague, Akio Morita, and on 7 May 1946, they founded a company called Tokyo Tsushin Kogyo K.K. (Tokyo Telecommunications Engineering Corporation). The company produced Japan's first tape recorder, called the Type-G.

In the early 1950s, Ibuka traveled to the United States, looking for a market for the company's tape recorder, and heard about Bell Labs' invention of the transistor. He convinced Bell to license the transistor technology to his Japanese company. Bell Labs agreed to do so while recommending Ibuka to produce Hearing aids using the transistor, then a popular application for the technology, suggesting that it would be difficult to apply the technology to radio. While most Japanese companies were researching the transistor for its military applications, Ibuka and Morita looked to apply it to communications. Although the American companies Regency Electronics and Texas Instruments built the first transistor radio as joint venture in 1954, it would be the Ibuka's company that made them commercially successful for the first time.

As an innovator 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 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. 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. The company marketed the radio as "pocketable", a Japanese-style English word the company came up with to highlight its portability and pocket-size. The word soon featured in English dictionary. University of Arizona professor Michael Brian Schiffer, PhD, 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. As a result of the popularity of transistor radios, which empowered privacy and individualism, the way people listen to radio or music has changed forever. Sony also launched the world's first integrated circuit radio, the ICR-100 in 1967. Following the first success in American consumer market, Tokyo Tsushin Kogyo changed its name to Sony in 1958 as people outside Japan struggled to pronounce the original name. Sony established Sony Corporation of America, the company's first subsidiary in America, in 1960. And in the same year, Sony made another innovation by releasing the world's first non-projection type all-transistor and portable television, Sony TV8-301. In 1961, Sony launched the world's first compact transistor VTR, the PV-100. In 1968, Sony launched the legendary color television set, Trinitron. The Trinitron was the reason that Sony had been the world's largest TV manufacturer in terms of annual revenue until 2006. In 1969, Sony launched Sony TC-50, a compact cassette recorder. NASA equipped every astronaut with the device from Apollo 7 onwards. Astronauts were required to use the recorder to log their missions but they also listened to music by inserting and playing the pre-recorded tapes. Masaru Ibuka also enjoyed listening to classical music using recorders, preluding the birth of Walkman. In October the same year, Sony released a prototype of the world's first commercial videocassette recorder. This led to the official launch of the VP-1100 two years later. Sony received the Emmy in 1973 for developing the Trinitron. This was the first Emmy awarded to an electronics. In 1975, Sony launched the Betamax, which took part and lost in the video format war.

Walkman, the first stereo cassette player, was launched in 1979. The year 1981 is considered as a starting point of the Digital Revolution with Sony launching the world's first Compact Disc player, the Sony CDP-101, with a Compact Disc (CD) itself, a new data storage format Sony and Philips co-developed. In that year, a 3.5-inch floppy disk structure was introduced by Sony and it soon became the de facto standard. Sony is also the company that produced the first color video camera using a CCD, the XC-1. The Sony Mavica, released in 1981, is a prototype of the world's first commercial electronic still camera. Sony played a significant role in the tech industry in the second half of the 20th century alongside Hewlett-Packard and IBM. Steve Jobs, fascinated by the company's innovative products, culture and work environment, was a big fan of Sony and regarded the company being in a league of their own, apart from the other comparable competitors. In 1991, Sony released the first c ommercial lithium-ion battery jointly with Asahi Kasei and had been the leader in the rechargeable battery industry until a massive defective battery scandal occurred in 2006. Sony introduced Memory Stick, a flash memory storage format, in 1998, a year earlier than the announcement of SD card. The Sony's format is considered as a yet another failed standard from the company. The list of Sony's unsuccessful attempts to make their proprietary formats universally adopted includes Betamax, MiniDisc or the well-known abbreviated term, the MD, and Universal Media Disc. In June 2006, Sony released the Blu-ray Disc format, a High-definition Optical disc format developed by the company in association with the Blu-ray Disc Association, in which Sony is a member of, alongside Philips, Panasonic and LG Electronics.

Worked examples

Example 1 — a first encounter with History of Sony

Start with the simplest possible case. Write down what History of Sony claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to History of Sony before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about History of Sony ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of History of Sony

In research
History of Sony appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses History of Sony in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
History of Sony is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of companies of Japan, History of computer companies, Sony, so understanding it makes those chapters shorter.
In everyday life
Look for History of Sony outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
