Sony's name blends Latin for sound with American slang for a young lad
Sony's founders wanted a short name Americans could say. Their initials, TTK, already belonged to a railway, and Totsuko tangled American tongues. So they combined sonus, the Latin root of sound, with sonny, 1950s slang for a boy. Their bank pushed back, but the invented word stuck in 1958.
The company started small in postwar Tokyo. In 1946 Masaru Ibuka opened an electronics shop inside a Nihonbashi department store with eight staff and ¥190,000 of capital, and on 7 May that year Akio Morita joined him to found Tokyo Tsushin Kogyo, or Tokyo Telecommunications Engineering. Its early achievements included Japan's first tape recorder, the Type-G. Another candidate name, Tokyo Teletech, was dropped when Morita found an American firm already using Teletech.
In Japan at the time, sonny boys was a borrowed phrase for smart, presentable young men, and the founders saw themselves that way. Spelling a Japanese company name in Roman letters rather than kanji was unusual, and the principal lender, Mitsui Bank, wanted something like Sony Electronic Industries. Morita refused, not wanting the name tied to a single industry, and the bank's chairman eventually agreed. The first product to carry the brand, the TR-55 transistor radio, came out in 1955, three years before the company itself was renamed.
Morita's instinct proved right as Sony spread far beyond electronics. Under president Norio Ohga, who had championed the compact disc, it bought CBS Records in 1988 and Columbia Pictures in 1989. The PlayStation, launched in 1994, became a core business that has sold over 650 million consoles. Not every period went smoothly: in the early 1980s one analyst declared that Sony's best days were behind it, and in 2005 Howard Stringer became the first foreigner to run a major Japanese electronics firm, cutting 9,000 jobs.
Today the parent is called Sony Group Corporation, a name adopted in 2021. In the 2025 fiscal year it earned about ¥12.48 trillion, with games and network services the largest slice.
