NBC Films

Background
NBC Films (also known as "NBC Enterprises, Inc.", who would later reform in late 1970s) was the production/distribution arm of the NBC Television Network for NBC off-network programs originally formed in 1952. In 1973, NBC later spun-off NBC Films and later sold it including the library to National Telefilm Associates because it was against the FCC regulations for a television network to distribute its programs under its own name. As of now, most of the library is currently handled by ViacomCBS, through CBS Television Distribution and Spelling Television Inc., except several episodes of You Bet Your Life by Buddy Hackett and non-public domain episodes by Groucho Marx are retained by NBCUniversal. Many others have fallen in the public domain.
