The original and most distinctive version of the iMac, the iMac G3, was a uniquely-shaped all-in-one desktop computer, fitted with a CRT monitor, and contained within a rather egg-shaped translucent plastic case. It was the case that was one of the biggest sources of comment at launch, with both the shape and the rather unexpected variety of colours causing comment and sparking a minor revolution in consumer electronics. The G3 underwent several updates until it was replaced by the iMac G4 in 2002. The iMac G4 had a base that was shaped like half a football, and was used to house all the main electronic componentry, with a monitor mounted on the top on a freely-moving arm.

The iMac G4 was replaced in 2004 by the iMac G5, which had all the circuitry and components located behind the glass screen, with the monitor attached to a plain stand which only allowed it to be tilted or raised. From the G5 onwards, the iMac had lost the rather eccentric shapes of the G3 and G4, and all the future iMac models resembled the conventional desktop computers we are familiar with today. Since 2006, the iMac has been running on Intel processors, and has been undergoing major updates roughly every 2 to 3 years, until the 7th version, the 27-inch iMac with 5K Retina Display and an aluminium unibody, which came about in 2014 and was updated in 2015 with a 21.5-inch version. A further addition to the iMac range was made in 2017, when the iMac Pro was released in December of that year.
