NBC was at the forefront of color programming because its parent company RCA manufactured the most successful line of color sets in the 1950s and, at the end of August 1956, announced that in comparison with 1955–56 (when only three of its regularly scheduled programs were broadcast in color) the 1956–57 season would feature 17 series in color. By 1959 RCA was the only remaining major manufacturer of color sets. CBS and ABC, which were not affiliated with set manufacturers and were not eager to promote their competitor's product, dragged their feet into color. CBS broadcast color specials and sometimes aired its big weekly variety shows in color, but it offered no regularly scheduled color programming until the fall of 1965. At least one CBS show, "The Lucy Show", was filmed in color beginning in 1963, but continued to be telecast in black and white through the end of the 1964–65 season. ABC delayed its first color programs until 1962, but these were initially only broadcasts of the cartoon shows "The Flintstones", "The Jetsons" and "Beany and Cecil". The DuMont network, although it did have a television-manufacturing parent company, was in financial decline by 1954 and was dissolved two years later.
