The IBM and family keyboard timeline is an illustrated overview of some of the most important events affecting IBM, Lexmark, Unicomp, Lenovo and Toshiba Global Commerce Solutions keyboards. This includes notable keyboard releases and withdrawals, corporate history like company founding, divestures and change in OEMs, and patents. Due to their relationship and impact on the keyboards around them, host devices such as personal computers, terminals, consoles and typewriters also appear throughout the timeline. 144 events have been recorded for the "show all" versions of the timeline.
