In November of 1937, NBC presented the first known pilot film, then called an "experimental." Over the years that followed, thousands of aired pilot films have appeared on TV either as stand-alone broadcasts or as part of a series. This reference work, the most complete guide to aired television pilot films ever published (or made available in any way), contains 2,470 alphabetically arranged programs, each with story information, performer and character cast listings, producers, air dates (where applicable), genre, and network or cable association. This edition also includes an appendix listing aired series spin-offs, like Agent Carter (2015), Fuller House (2016) and Magnum P.I. (2018). (Information on unaired pilot films can be found in the companion volume, Encyclopedia of Unaired Television Pilots, 1945–2018.)
