=== QuickTime 5.x ===
QuickTime 5 was one of the shortest-lived versions of QuickTime, released in April 2001 and superseded by QuickTime 6 a little over a year later. This version was the last to have greater capabilities under Mac OS 9 than under Mac OS X, and the last version of QuickTime to support Mac OS versions 7.5.5 through 8.5.1 on a PowerPC Mac and Windows 95.  Version 5.0 was initially only released for Mac OS and Mac OS X on April 14, 2001, and version 5.0.1 followed shortly thereafter on April 23, 2001, supporting the classic Mac OS, Mac OS X, and Windows.<ref>{{cite web | title=Timeline of QuickTime Updates at the Apple Museum | url=http://www.theapplemuseum.com/index.php?id=41 | access-date=January 6, 2007 |url-status=dead |archive-url=https://web.archive.org/web/20111130002506/http://www.theapplemuseum.com/index.php?id=41 |archive-date=November 30, 2011 }}</ref> Three more updates to QuickTime 5 (versions 5.0.2, 5.0.4, and 5.0.5) were released over its short lifespan.
