Sony
On May 7, 1946, Morita and Ibuka founded Tokyo Tsushin Kogyo Kabushiki Kaisha (Tokyo Telecommunications Engineering Corporation, the forerunner to Sony Corporation) with about 20 employees and initial capital of ¥190,000. Ibuka was 38 years old, Morita 25. Morita's family invested in Sony during the early period and was the largest shareholder.
In 1949, the company developed magnetic recording tape and in 1950, sold the first tape recorder in Japan. In 1957, it produced a pocket-sized radio (the first to be fully-transistorized) and in 1958 Morita and Ibuka made the decision to rename their company Sony (sonus is Latin for sound, and Sonny-boys is Japanese slang for "whiz kids"). Morita was an advocate for all the products made by the Sony Corporation. He helped sell his new radio by claiming that it was "pocket sized" and had the ability to fit in a normal shirt pocket. However, the radio was slightly too big to fit in a shirt pocket, so Morita made his business men wear shirts with slightly larger pockets giving the radio a "pocket sized" appearance. In 1960 it produced the first transistor television in the world. In 1979 the Walkman was introduced, making it the world's first portable music player. In 1984 Sony launched the Discman series which extended their Walkman brand to portable CD products.
In 1960, the Sony Corporation of America was established in the United States. In 1961, the Sony Corporation of America was the first Japanese company to be listed on the New York Stock Exchange. Sony bought Columbia Records and other CBS labels in 1988 and Columbia Pictures in 1989.
On November 25, 1994, Morita announced his resignation as Sony chairman, after suffering a cerebral hemorrhage while playing tennis. His successor, Norio Ohga, had joined the company after sending Morita a letter denouncing the poor quality of the company's tape recorders.
