As a historical note. A lot of video/audio in this era was laserdisc.I worked on a touch screen playback system that used laserdisc. In 1988 this was state of the state of the art . The same system was in the awesome gsme DragonsLair, Space Ace, and. M.A.C.H. 3

Digital video was quite a number of years out:

Autodesk flic came out in 89/90. - the famous jolt cola can

Apple shipped QuickTime in late 91

Microsoft shiipped VfW in 1992

Mpeg1 chipsets became common in 1993
