The Globe and Mail reports in its Thursday edition that on Jan. 9, 2001, Apple chief executive officer Steve Jobs appeared at the Macworld Expo in San Francisco to announce the release of iTunes. The Globe's Brad Wheeler quotes Mr. Jobs telling the crowd, "There is a music revolution happening right now," assessing a state of digital music that involved compact discs, on-line piracy and complicated computer-file applications. iTunes was an insurgent new media player and personal-music-library advancement billed as the world's "best and easiest-to-use jukebox software." If phonograph inventor Thomas Edison wasn't rolling over in his grave, he was at least propped up on one elbow, listening intently. By the end of the year, the hand-held iPod player was introduced, and, in the spring of 2003, Apple flung open the virtual doors to its on-line iTunes Store, where songs sold for 99 cents. The music industry was in upheaval. Songs became king: Full albums need not be purchased to own a track. By 2011, Apple had sold 10 billion digital songs, as music lovers bypassed bricks-and-mortar retailers. Eventually, however, personal music "ownership" became passe. On-line music-streaming services (including Apple Music) now hold sway.
