Apple and IBM competed for similar users (VisiCalc started on the Apple ][), Commodore was competing against consoles and crappier computers. Commodore was eventually killed by PC clones -- IBM PCs were FAR too expensive for families to buy to play games on. (IBM PCs were more generally as expensive as Macs -- clones drove prices down, with IBM maintaining obscene prices until its brand name meant nothing). Commodore continued to have huge success with the Amiga -- but less so in the US than Europe and Australia. My recollection was of game stores being C64 and cartridges and a bunch of lesser companies, and then Amiga and IBM gradually taking over, with IBM only becoming dominant as Commodore finally succumbed to mismanagement in the early 90s (after commodore when bankrupt, it was revealed that during the years when the Amiga was the world's most popular home computer, Commodore never turned a profit).
