Most people didn’t get a VCR—either a VHS or a Betamax—until the mid-‘80s. But had electronics giant RCA had better luck, home video could’ve been a part of American life in the mid-1960s. In 1964, the company developed capacitance electronic disc technology, which allowed them to score optical and audio data—you know, movies—on grooved discs that were basically records but which spun at a rate of 450 times a minute. A needle read the groove, and converted the data embedded within to a video signal that could be displayed on a TV. Numerous technical delays meant RCA didn’t get its SelectaVision to stores until 1981, at which point VHS and Betamax were fighting it out for consumer loyalty. By 1986, when RCA pulled the plug on SelectaVision, only 150,000 of the players had been sold.
