The Westinghouse H840CK15 was the second consumer all-electronic color television set offered for sale in the United States on February 28, 1954.[1] The set was discontinued about six months after its introduction[2] because of larger and less expensive 19 and 21-inch color sets becoming available in July and December 1954 such as Motorola and RCA. The set used the 15GP22 cathode ray tube.
