The iMac is a range of all-in-one Macintosh desktop computers designed and built by Apple Inc. It has been a large part of Apple's consumer desktop offerings since its introduction in 1998, and has evolved through four distinct forms. In its original form, the iMac G3, the iMac was gum drop- or egg-shaped with a CRT monitor, mainly enclosed by colored, translucent plastic. The second major revision, the iMac G4, moved to a design of a hemispherical base containing all the main components and an LCD monitor on a freely moving arm attached to the top of the base. The iMac G5 and the Intel iMac placed all the components immediately behind the display, creating a slim design that tilts only up and down on a simple metal base. The current iMac shares the same form as the previous models, but is now thinner and uses brushed aluminum and black-bordered glass for its case.

Like other Apple products, the iMac enjoys a relatively high profile in popular culture due to its distinctive aesthetics and Apple's successful marketing Fact: date=July 2008. The iMac and other Macintosh computers can also be seen in various movies, commercials, and TV shows (both live action and animated). The iMac has also received considerable critical acclaim, including praise from technology columnist Walt Mossberg as the “Gold Standard of desktop computing"; Forbes Magazine described the original candy-colored line of iMac computers as being an “industry-altering success”. The first 24" Core 2 Duo iMac received CNET's “Must-have desktop” in their 2006 Top 10 Holiday Gift Picks.

On March 3, 2009, Apple updated its offerings for the iMac, featuring NVIDIA chipsets and the new Mini-DisplayPort that has become standard in all new Apple computers.

Design

The announcement of the iMac was a source of discussion and anticipation among commentators, Mac fans, and detractors. Opinions were divided over Apple's drastic changes to the Macintosh hardware. At the time, Apple was trying to improve its retail strategy. Apple declared that "the back of our computer looks better than the front of anyone else's".

Apple declared the 'i' in iMac to stand for "Internet".Attention was given to the out-of-box experience: the user needed to go through only two steps to set up and connect to the Internet. "There's no step 3!" was the catch-phrase in a popular iMac commercial narrated by actor Jeff Goldblum. Another commercial, dubbed ”Simplicity Shootout”, pitted seven-year-old Johann Thomas and his border collie Brodie, with an iMac, against Adam Taggart, a Stanford University MBA student, with an HP Pavilion 8250, in a race to set up their computers. Johann and Brodie finished in 8 minutes and 15 seconds, whereas Adam was still working on it by the end of the commercial. Apple later adopted the ‘i' prefix across its consumer hardware and software lines, such as the iPod, iBook, iPhone and various pieces of software such as the iLife suite and iWork.
