Launch
Apple introduced it on August 31, 1999 at the Seybold San Francisco keynote alongside the Power Mac G4, per the official announcement reproduced by MacTech: a 22-inch LCD panel, "the largest ever brought to market", with the viewing area of a 24-inch flat CRT, letterbox 1600×1024 format and 16.7 million colors. Per Wikipedia, it was released on September 1, 1999 as model M5662 with DVI input and an easel-style stand.
Marketing
In July 2000, at Macworld Expo New York, the family was redesigned with crystal-clear enclosures to match the Power Mac G4 Cube and G4, and debuted the Apple Display Connector, a single cable carrying video, USB and power, with a two-port USB hub, per Apple's press release. That release priced the 22" at $3,999 and called it "the largest all-digital LCD flat panel ever brought to market", able to show two full pages of text and graphics at once.
Flaws and fixes
ADC simplified the desk but tied the monitor to Macs with that connector or to an adapter, a transition Apple acknowledged in 2002 with a DVI-to-ADC converter. The 22" was discontinued on January 28, 2003, when the 20-inch Cinema Display (1680×1050) offered more pixels of workspace for $1,299, per that day's Apple release and Wikipedia.
