Test films, pilots, trial series, limited runs, summer tryouts - by whatever name, television networks have produced thousands of experimental shows that never made it into the regular line-up. Some were actually shown, but failed to gain an audience; many others never even made it on the air.This work includes over 3,000 experimental television programs, both aired and unaired, that almost became a series. Each entry includes the name of the show, length, network, air date (if appropriate), a fact-filled plot synopsis, cast, guest stars, producer, director, writer, and music coordinator. Information for this work was gathered primarily by watching the shows, reading years' worth of press releases, and using sources such as ""TV Guide"" and ""Variety"" to augment the primary research.
