iTunes is a media player made by Apple. It came out on January 10, 2001, at the Macworld Expo in San Francisco.[1] iTunes is used for playing and sorting music and video files. It also lets users see and change what is on their iPod or iPhone. iTunes is a free download for Mac OS X and Microsoft Windows from Apple's website but requires a subscription. The download is also included with QuickTime, a program used to play videos. It also comes with all Apple Macintosh computers, and some HP and Dell computers. However, on 3 Jun 2019, Apple announced that iTunes would not be available on macOS Catalina.
