MacExpo London was a trade show dedicated to the Apple Macintosh and iPod which was held annually in London, United Kingdom at the Olympia Exhibition Centre from 2002 to 2007. It was a major part of Apple's calendar. In 2004, Macworld UK, part of the IDG UK division of IDG, created two Macworld Conference events on its own: one standalone conference, and one conference adjoining the MacExpo trade show in London. In 2005, the show attracted 25,000 visitors and 185 exhibitors.
