As a Japanese multinational corporation headquartered in Tokyo, Sony's diversified business includes gaming, entertainment and financial services and is notable as a leading manufacturer of consumer and professional electronics.

Sony was founded by Masaru Ibuka and Akio Morita in the wake of World War II (1947) as a company called Tokyo Tsushin Kogyo. They built Japan's first tape recorder called the Type-G and in 1958 changed the company name to ‘Sony’ chosen as a mix of two words. The Latin word ‘sonus’ which is the root of sonic and sound, and ‘sonny’, a common 1950s slang term which connoted smart and presentable young men.

The TR-63 radio cracked open the US market and launched a new industry of consumer microelectronics. American teens began buying portable transistor radios in huge numbers, helping to propel the fledgling industry from 100,000 units in 1955 to 5 million units by the end of 1968.

Sony significantly improved perceptions of "made in Japan" products. Known for production quality, they were able to charge above-market prices for consumer electronics and resisted lowering prices.

Today, Sony is among the semiconductor sales leaders and as of 2016, the fifth-largest television manufacturer in the world.
