From a bomb-damaged Tokyo department store to Walkman, PlayStation and image sensors: Sony at 80
Sony’s first workplace was inside a damaged department-store building in post-war Tokyo.
Masaru Ibuka and Akio Morita established Tokyo Tsushin Kogyo K.K., or Tokyo Telecommunications Engineering Corporation, on 7 May 1946 with roughly 20 employees and 190,000 yen in capital.
The company’s founding prospectus described an ambition to create an “ideal factory” where engineers could work freely and contribute to Japanese culture through technology.
The first commercial successes were about recording sound
Sony’s predecessor developed magnetic recording tape and launched Japan’s first tape recorder, the G-Type, in 1950.
These products established expertise in audio and miniaturisation that would reappear throughout the company’s history.
The transistor radio took the company beyond Japan
Tokyo Tsushin Kogyo launched the TR-55, Japan’s first transistor radio, in 1955.
Smaller transistor radios were easier to carry than vacuum-tube sets and fitted Sony’s ambition to create personal electronics rather than only household furniture.
The company adopted the Sony name in 1958, choosing a short brand that could travel internationally.
Trinitron made picture quality a Sony signature
Sony launched the Trinitron colour television in 1968.
The display technology built a reputation for image quality and became one of the company’s defining consumer-electronics franchises for decades.
The Walkman changed where music could be consumed
Sony introduced the TPS-L2 Walkman in 1979.
The device removed recording functionality and focused purely on portable stereo listening, despite internal doubts that consumers would buy a player that could not record.
It became a global success and turned “Walkman” into a category-defining brand.
Music formats pulled Sony into industry standards
Sony worked with Philips on compact-disc technology and launched the CDP-101, the first commercial compact-disc player, in 1982.
The company later backed technologies including MiniDisc, while also learning that not every proprietary format would win.
Buying content changed Sony from electronics maker to entertainment group
Sony acquired CBS Records in 1988 and Columbia Pictures in 1989.
Those transactions gave the company major music and film businesses.
The strategy created a rare combination of hardware platforms and entertainment rights inside one corporate group.
PlayStation turned a failed partnership into a gaming empire
Sony entered the console market with the original PlayStation in 1994 after an earlier project with Nintendo collapsed.
PlayStation became one of Sony’s most important franchises, expanding through consoles, online services, studios and digital distribution.
Gaming eventually became a central part of the group’s economics.
Image sensors created a less visible technology powerhouse
Sony began developing CCD image sensors in the 1980s and later became a leading supplier of CMOS image sensors.
Its sensors are used in smartphones, cameras, vehicles and industrial systems, including devices made by other brands.
This component business means Sony’s technology influence extends beyond products carrying the Sony logo.
Financial services and entertainment made Sony unusually diversified
Sony also built businesses in music, film, anime and financial services.
The company reorganised as Sony Group Corporation, reflecting an identity broader than consumer electronics.
Eighty years later, Sony still connects engineering with entertainment
As Sony marked its 80th anniversary in 2026, the company’s portfolio included PlayStation, music, pictures, electronics, imaging and sensing.
Hiroki Totoki serves as president and chief executive of Sony Group.
The thread through the company’s history is not one product category but a repeated attempt to create technologies that change how people experience media.
