How world's most famous companies got their names?

Sony: from the Latin word ‘sonus’ meaning sound, and ‘sonny’ a slang word used by Americans to refer to a bright youngster, “since we were sonny boys working in sound and vision”, said Akio Morita. The company was founded as Tokyo Tsoshiu Kogyo KK (Tokyo Telecommunications Engineering Corporation) in 1946, and changed its name to Sony in 1958. Sony was chosen as it could be pronounced easily in many languages.
