Work on AppleBus was quickly re-directed to networking purposes, and evolved into the AppleTalk system that was released in 1985
ADB was rapidly replaced by USB as that system became popular in the late 1990s; the last external ADB port on an Apple product was in 1999, though it remained as an internal-only bus on some Mac models into the 2000s
The first Macintosh to move from ADB was the iMac in 1998, which featured USB in its place
The last Apple computer to have an ADB port was the "Yosemite" Power Macintosh G3 in 1999
No machines being built today use ADB for device interconnection, but up to February 2005, PowerBooks and iBooks still used the ADB protocol in the internal interface with the built-in keyboard and touchpad
