=== First non-linear editor ===
The first truly non-linear editor, the [[CMX 600]], was introduced in 1971 by [[CMX Systems]], a joint venture between [[CBS]] and [[Memorex]].<ref>{{citation |archive-url=https://web.archive.org/web/20130410092334/http://sundialmedia.com/sait/articles/found_a/heat_f.htm |archive-date=2013-04-10 |url=http://sundialmedia.com/sait/articles/found_a/heat_f.htm |title=The History of Digital Nonlinear Editing |work=Facer Ezine}}</ref><ref>{{citation |archive-url=https://web.archive.org/web/20071021231834/http://nonlinear.info/N4.history.pdf |archive-date=2007-10-21 |url=http://nonlinear.info/N4.history.pdf |title=A Brief History Of Electronic Editing |work=Non Linear}}</ref> It recorded and played back black-and-white analog video recorded in "[[skip-field]]" mode on modified [[disk pack]] drives the size of washing machines that could store a half-hour worth of video & audio for editing. These disk packs were commonly used to store data digitally on mainframe computers of the time. The 600 had a console with two monitors built in. The right monitor, which played the preview video, was used by the editor to make cuts and edit decisions using a [[light pen]]. The editor selected from options superimposed as text over the preview video. The left monitor was used to display the edited video. A DEC [[PDP-11]] computer served as a controller for the whole system. Because the video edited on the 600 was in low-resolution black and white, the 600 was suitable only for offline editing.
