Sony began in the wake of World War II. In 1946, Masaru Ibuka started an electronics shop in Shirokiya, a department store building in the Nihonbashi area of Tokyo. The company started with a capital of ¥190,000 and a total of eight employees. On 7 May 1946, Ibuka was joined by Akio Morita to establish a company called Tokyo Tsushin Kogyo. The company built Japan's first tape recorder, called the Type-G. In 1958, the company changed its name to "Sony".

On 1 April 2021, Sony Corporation renamed Sony Group Corporation. On the same day, Sony Mobile Communications Inc. absorbed Sony Electronics Corporation, Sony Imaging Products & Solutions Inc., and Sony Home Entertainment & Sound Products Inc. and changed its trade name to Sony Corporation.

As of 2020, Sony had $75.972 billion of revenue and 111,700 employees.
