Answer: Video Footage
Long before LaserDisc and even before DVDs, RCA had a video system based on discs. RCA's Capacitance Electronic Disc (CED), invented in the 1
It looked like a record, shimmering in the light like the surface of an optical disc, leaning on a needle to play an analog signal. From a technological point of view, it was a great success and a miracle. The video was of high quality for the time (the lower VHS quality for a 1960s-1970s format was not to be laughed at), the movies recorded on it had chapters, the ability to jump back and forth across the entire movie, and a variety of features were not available at this time (but standard on later laser discs and DVDs).
However, a technological marvel alone is not enough, and the CED system was a commercial mistake. Despite a competitive edge, support from major movie studios, and support from production and distribution channels, the system remained largely unknown. Due to conflicts over RCA, inadequate marketing, technical difficulties, and the arrival of the LaserDisc, Betamax, and VHS formats, the CED system has never been successful, costing RCA an estimated $ 600 million in losses.
