The iMac is a range of all-in-one Macintosh desktop computers designed and built by Apple Inc. It has been the primary part of Apple's consumer desktop offerings since its debut in August 1998 (shipped; introduced June 1998), and has evolved through six distinct forms.^[1]

The second major revision, the iMac G4, moved the design to a hemispherical base containing all the main components and an LCD monitor on a freely moving arm attached to it.
