Tokyo Telecommunications Engineering Corporation

In 1945, after World War II, Masaru Ibuka started a radio repair shop in a bombed-out building in Tokyo. The next year he was joined by his colleague Akio Morita, and they founded a company called Tokyo Tsushin Kogyo K.K., which translates in English to 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 looked to apply it to communications. While the American companies Regency and Texas Instruments built transistor radios first, it was Ibuka's company that made the first commercially successful transistor radios.

In August 1955, Sony produced its first coat-pocket sized transistor radio they registered as the TR-55 model. In 1956, Sony reportedly manufactured about 40,000 of its Model TR-72 box-like portable transistor radios and exported the model to North America, the Netherlands and Germany.

That same year they made the TR-6, a coat pocket radio which was used by the company to create its "SONY boy" advertising character. The following year, 1957, Sony 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 1958. However, this huge growth in portable transistor radio sales that saw Sony rise to be the dominant player in the consumer electronics field was not because of the consumers who had bought the earlier generation of tube radio consoles, but was driven by a distinctly new American phenomenon at the time called Rock and Roll.

When 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 Morita discovered that Americans had trouble pronouncing that name, during his visit to the United States. 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 the Latin word sonus, which is the root of sonic and sound, the English word "sunny", and from the word Sonny-boys which is Japanese slang for "whiz kids". However "Sonny" was thought to sound too much like the Japanese saying soh-nee which means business goes bad. Morita pushed for a word that does not exist in any language so that they could claim the word "Sony" as their own (which paid off when they sued a candy producer who also used the name who claimed that "Sony" was just an existing word in some language).

At the time of the change, it was extremely unusual for a Japanese company to use Roman letters instead of Kanji to spell its name. 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.

As a result of this persistence, Sony has now developed into a leading international manufacturer producing a variety of products throughout the electronics market, music and gaming industries, film, finance and many more besides.
