Updates
The iMac line was continually updated after initial release. Aside from increasing processor speed, video RAM, and hard-disk capacity, Apple replaced Bondi blue with new colors—initially in January 1999 with blueberry, strawberry, tangerine, grape, and lime; later other colors, such as graphite, ruby, sage, snow, and indigo, "Blue Dalmatian" and "Flower Power" patterns.
A later hardware update created a sleeker design. This second-generation iMac featured a slot-loading optical drive, FireWire, "fanless" operation (through free convection cooling), and the option of AirPort wireless networking. Apple continued to sell this line of iMacs until March 2003, mainly to customers who wanted the ability to run the older Mac OS 9 operating system.
USB and FireWire support, and support for dial-up, Ethernet, and wireless networking (via 802.11b and Bluetooth) soon became standard across Apple's entire product line. In particular, the high-speed interface, FireWire, corrected the deficiencies of the earlier iMacs.
The iMac CRT model, now targeted at the education market, was renamed the iMac G3, and kept in production alongside the iMac G4 successor until the eMac was released.
As Apple continued to release new versions of its computers, the term iMac continued to be used to refer to machines in its consumer desktop line.
