Radio Corporation of America (RCA) begins producing the first mass-produced all-electronic color television receiver, the RCA CT-100. The release comes just months after a limited release of the first NTSC television camera, the model RCA TK-40, in 1953 and just days after RCA began shipping the first commercially available color television camera, the TK-40A, from its plant in Camden, New Jersey. The receivers, which are manufactured in Bloomington, Indiana, each feature an eleven and a half-inch wide picture produced by a fifteen-inch picture tube, thirty-six vacuum tubes, and a 12½ inch screen. Westinghouse released a model of color television several weeks earlier, but only one of the hand-assembled sets sold in the month following its release. Though RCA will loose money on every unit sold, the color television sets retail for US$1,000, roughly one-third to one-half the cost of a new car, due to the extraordinary costs involved in producing picture tubes. As a result of the model’s prince, only about 4,000 of the sets will ever be sold. It will take more than a decade for color televisions to become popular enough for color broadcasts to become a regular part of network programming.
