What started the whole "i" movement?
How about How did Apple choose the 'i' naming convention?


  We returned with five names, one of which we all loved: iMac. Each option came with a presentation board briefly describing why it was a good name. For iMac, it was obviously all about the i. Most important, it stood for Internet. But it also stood for other valuable i things, like individual, imagination, i as in me, etc. It also did a pretty good job of laying a solid foundation for future product naming. The “i” naming nomenclature became so pervasive Steve became the iCEO for a number of years. There was even a Time magazine story that cemented this title.
