Sony was established in the wake of World War II in 1946, when engineer Masaru Ibuka joined forces with physicist Akio Morita to form a company aimed at repairing electronic equipment. Originally named Tokyo Tsushin Kogyo K.K., which means Tokyo Telecommunications Engineering Corporation, the company developed Japan's first tape recorder in 1950. In 1958, the company officially changed its name to Sony, derived from the Latin word 'sonus,' meaning sound, and 'sonny,' a colloquial term used in America to refer to a young boy. Over decades, Sony expanded its business globally, pioneering many technologies and products such as the Trinitron television and Walkman portable music player, which established Sony as a household name across the world.
