iLife is a suite of software applications for Mac OS X developed by Apple for organizing, editing, and publishing photos, movies, and music. The suite comprises five applications: iPhoto, iMovie, iDVD, GarageBand, and iWeb.

The most recent version, iLife '11, was publicly announced on October 20, 2010 at the Back to the Mac event held by Apple. The suite is available as a standalone product and is included with all new consumer Macintosh computers.

iMovie is the oldest of the applications included with iLife. It was marketed by Apple as an easy-to-use video editing application that allowed novice users to quickly create professional-quality movies. The first version of the software was released in October 1999 and bundled with the iMac DV. On April 28, 2000, Apple began allowing users to download iMovie free of charge from its website. iMovie remained free until 2003, when it became part of the first iLife release, which was sold for $49. Apple continued to update and develop the existing iMovie software until the release of iLife '08 in 2007, when a new version, iMovie '08, was released. iMovie '08 was completely rewritten as a new application and introduced significant changes to the user interface.
