"C & C Movietime U.S.A." goes back to when the RKO Pictures library first popped up on television!
In 1955, General Tire (which also owned WNAC-7 Boston, WGTH-18 Hartford (which would soon be sold-off), WOR-9 New York, WEAT-12 West Palm beach, WHBQ-13 Memphis and KHJ-9 Los Angeles) purchased the RKO Pictures studio and film library from Howard Hughes for about $25 million.
The purpose was two fold: General Tire wanted to revitalize the RKO studios so it could produce movies and TV shows (the later likely for syndication, with what would soon become the RKO General TV stations getting the rights to these syndicated shows in their markets); and for General to acquire the RKO film library.
C & C was a company owned by Matty Fox which distributed the RKO movies nationally, except for the six cities where General Tire owned TV stations. In those cities, the RKO film library went to the RKO General TV stations.
Initially, only those RKO movies made through 1948 were released to TV (there was a "Gentleman's Agreement" at the time that feature films made after 1948 would not yet be released to TV), but eventually, the post-1948 films "saw the light of day" on the tube.
In the cases of WOR and KHJ (and WGTH--later WHCT--after RKO re-acquired the station and ended the over-the-air pay-TV experiment), the better RKO movies were shown in prime-time since these stations were independents. The others were network affiliates, so these films were broadcast late at night or on weekend afternoons.
In the case of my hometown of Boston, WNAC showed RKO pictures (and occasionally, films from other studios or distributors) under the title "Cinema 7". Circa 1961, WNAC carried "Cinema 7" nightly at 11:15 P.M. (after the late news), a double feature that would usually run until 2:45 or 3 A.M.; and a Sunday-afternoon double-feature starting at 12 Noon and running until 3 or 3:30 P.M.
