The iMac first went on sale on 15 August 1998 – twenty years ago tomorrow. Since it launched there have been seven distinct designs as the iMac has evolved through assorted colours, shapes, and sizes, via a multitude of materials, to the sleek silhouette we know today.

When the iMac was introduced it caused shockwaves in the industry and became a design icon. To celebrate two decades of Apple’s all-in-one computer, we have 10 facts about the iMac as well as a history of the iMac in pictures.

iMac Facts

1. The iMac was first introduced by Apple’s co-founder and CEO the late Steve Jobs at an event on 6 May 1998, with Apple’s Steve Jobs saying that it was designed for the “number one use consumers tell us they want a computer for, which is to get on the Internet, simply and fast.” The iMac then went on sale on 15 August 1998 and became the best-selling computer that Christmas.
2. The iMac was credited with saving Apple from certain death (although Steve Jobs, who had returned to the company a year previously also takes much of the credit for that). 
3. The iMac was designed by Jonathan Ive. Ive, who is from Chingford in North East London, has since been knighted (so, officially he is Sir Jonathan Ive). He still works for Apple as the Chief Design Officer.
4. The name iMac was dreamed up by Ken Segall who worked at Apple’s ad agency. Jobs wanted to call it MacMan, luckily Segall convinced him otherwise. A few years ago we met Ken Segall, this is what he had to say about the name iMac.
5. The original iMac commercial was narrated by actor Jeff Goldblum.
6. The I in iMac stands for internet and was Apple’s first ‘i’ product. Back in 1998 the internet was rapidly expanding and the first internet weblogs were beginning to appear. Apple billed the iMac as an easy way to get connected to the internet, in just two steps, according to an advertisement of the time. Apple adopted the ‘i’ prefix across much of its consumer lines, including iPod, iPhone, iPad, iLife, iWork and iTunes.
7. When the original iMac shipped on 15 August 1998 it offered a 233HMz PowerPC G3 processor, 32MB RAM, 4GB hard drive, and a 15-inch monitor. It cost $1,299.
8. The original iMac introduced USB to the masses as the first Macintosh computer to feature a USB port. It also killed off the floppy drive.
9. Apple’s original iMac design came in a variety of colours: Bondi Blue, then Lime, Strawberry, Blueberry, Grape, Tangerine, and later on Blue Dalmatian and Flower Power – unlike the rest of the PC industry which at the time tended to come in beige.
10. At the Macworld Conference and Expo in January 2006 Apple announced that it was moving from PowerPC chips to Intel and marking the occasion it launched a new iMac with an Intel Core Duo processor.
