Steve Jobs saw the opportunity to open a digital marketplace for music due to the rising popularity of easily downloadable tracks.[8][9][10][11] In 2002, Jobs made an agreement with the five major record labels to offer their content through iTunes.[12] The iTunes Store was introduced by Jobs at the company's Worldwide Developers Conference in April 2003.[13][14] It was initially available on Mac computers and the iPod,[15] and was later expanded to Microsoft Windows in October 2003.[16]
