Here is an interesting article about company names and how they came about. Finally and interesting article worth reading from Techtree.
Jobs was three months late in filing a name for the business, and he threatened to call his company Apple Computers if his colleagues didnt suggest a better name. As you can guess, they didnt come up with anything better and the rest is history. Other theories are that Jobs wanted his company to feature before Atari in the phone book, while yet another suggestion is that it was a tribute to Apple Records, which was the music label of the Beatles.
