Sony Group Corporation, commonly referred to as simply Sony, is a Japanese multinational mass media & conglomerate headquartered at Sony City in Minato, Tokyo, Japan. The Sony Group encompasses various businesses, including electronics, imaging and sensing, entertainment, video games, finance, and others. Sony was founded in 1946 as initially Tokyo Tsushin Kogyo K.K. by Masaru Ibuka and Akio Morita. In 1958, the company adopted the name Sony Corporation. Initially an electronics firm, it gained early recognition for products such as the TR-55 transistor radio and the CV-2000 home video tape recorder, contributing significantly to Japan's post-war economic recovery. After Ibuka's retirement in the 1970s, Morita served as chairman until 1994, overseeing Sony's rise as a global brand recognized for innovation in consumer electronics. Landmark products included the Trinitron color television, the Walkman portable audio player, and the co-development of the compact disc. Expanding beyond electronics, Sony acquired Columbia Records in 1988 and Columbia Pictures in 1989, while also entering the home video game console market with the launch of the PlayStation in 1994.
