...applications of the laser-type videodisc are limited only by the imagination, and applications even more innovative than the one in Knoxville have been developed. Examples...
...every day at the U.S. Pavilion at Energy Expo '82 (a.k.a. the Knoxville, Tenn., World's Fair) as exuberant children and their more inhibited parents discover that TV viewing is passive no longer. The technology is called the interactive videodisc: the symbiosis of the computer and the laser-vision disc...
...Selecta Vision, 15 years and $200 million in the making. Not a truly innovative technology, Selecta Vision is essentially a phonograph that uses a mechanical stylus to play prerecorded movies. Its costly debut obscured the second type of videodisc: the infinitely more versatile laser-vision disc, designed for the videodisc player introduced by Magnavox in 1978. Manufactured by Pioneer, Sony and the 3M Co., the laser-vision disc makes flexible interaction possible...
More sophisticated and more expensive than the stylus disc, the laser-vision disc not only offers enormous storage capacity but provides random access and perpetual durability. A low-powered laser beam "reads" billions of microscopic pits of information imprinted on the smooth, shimmering disc. On each side are stored 54,000 images, any one of which can be called up instantly on command. The stylus and laser systems are incompatible, which leads to a great deal of consumer confusion. Moreover, unlike the video cassette recorder, the systems cannot record from television. Currently there are three videodisc machines on the market...

These, however, were most probably British missiles; the U.S.-supplied Sidewinders were apparently used only to replenish inventories in Britain. Also supplied were highly effective laser target indicators for British ground forces and a radar system for the Royal Navy's Sea wolf surface-to-air missiles...
