Holiday Film Festival was a Thanksgiving Day science fiction film series, aired annually from 1976 to 1985 on WOR-TV (channel 9) in New York City (now WWOR-TV in Secaucus, New Jersey).
For most of these broadcasts, the sponsors were local electronics chain Crazy Eddie and toy store Play World.
At least for the 1979 line-up, in addition to the many ads Play World ran for the store, they sponsored a "TV crossword game" during commercial breaks, in which viewers could win a shopping spree or gift certificates.
Shortly after the 1985 program, WOR-TV lost the broadcast rights to the RKO library and Mighty Joe Young, King Kong, and Son of Kong could no longer be broadcast.
This was due to parent company RKO General agreeing to sell Channel 9 to MCA Inc. in 1986 (the sale was finalized in 1987).
