One of the forgotten local movie shows (at least I.M.H.O.) has been Movie 4 on WNBC-TV in New York, which ran from 1956 to 1974. This title was confirmed to have also been used by WRC-TV in Washington, DC; but I was curious if anyone had any info on whether this was also used from the late 1950's until at least the early 1970's by KRCA/KNBC in Los Angeles.
I do know that among the other NBC O&O's, this format title was adapted to the channel numbers in other cities that differed from those three. For example, WNBQ/WMAQ-TV had Movie 5; and when they owned what they called WRCV-TV in Philadelphia, their movie show was titled Movie 3. (However, from what I've been apprised, this title was not brought by NBC to Cleveland at the time their second wave of ownership of what became WKYC-TV commenced in 1965, instead retaining The Early Show title from Westinghouse/KYW-TV days.)
