A Late 1980s Promotional Video for a Computer Sound Card Featuring State-of-the-Art Bleeps and Bloops
YouTube user GreatMewtwo uploaded what appears to be a late 1980s promotional video for sound cards from Ad Lib, a Canadian manufacturer known for the widespread adoption of its sound cards by the video game industry in the late 1980s and early 1990s. Specifically, the AdLib Music Synthesizer Card did quite well for the company, though it did not stop them from filing for bankruptcy in 1992 in the face of competition from the Sound Blaster family of sound cards.
