October 2003: 'Hell froze over'

Apple's iTunes Music Store came on the scene in April 2003 with a library of 200,000 tunes, including exclusives from 20 artists, including Bob Dylan and U2. "We were able to negotiate landmark deals with all of the major labels," Jobs said at the launch. "There is no legal alternative that's worth beans."

At the time, iTunes songs were available only for Macs running the OS X operating system and for iPods. In October of that year, Apple introduced the Windows version of the iTunes software (which had been out since 2001 for Apple gear) and the iTunes store, a foray into the Microsoft Windows environment that Jobs commemorated with the phrase "Hell froze over."
