Sony created the PlayStation brand and is headquartered in Tokyo, Japan.
Sony was founded in 1946 as Tokyo Tsushin Kogyo by Masaru Ibuka and Akio Morita. The company adopted the name Sony in 1958 and grew into a multinational business spanning electronics, entertainment, financial services, music, and film.
The original PlayStation was released in Japan in December 1994 and later launched in other markets. It became a major competitor in the home-console industry and developed into a broad ecosystem of consoles, games, online services, accessories, and studios.
Sony is more diversified than a simple video-game company. Its businesses include Sony Pictures Entertainment, Sony Music Entertainment, image sensors, cameras, televisions, and financial operations in Japan. This breadth helps explain why investors evaluate Sony as a large multinational corporation rather than only as the maker of PlayStation consoles.
