Television pilot A television pilot (also known as a pilot or a pilot episode and sometimes marketed as a tele-movie) is a standalone episode of a television series that is used to sell the show to a television network. At the time of its creation, the pilot is meant to be the testing ground to gauge whether a series will be successful, and is therefore a test episode of an intended television series. It is an early step in the development of a television series, much like pilot studies serve as precursors to the start of larger activity. In the case of a successful television series, the pilot is commonly the very first episode that is aired of the particular series under its own name. A "back door pilot", is an episode of an existing successful series, that features future tie-in characters of an up-and-coming television series or film. The purpose of the "back door pilot" is to introduce the characters to an audience before the creators decide on whether they want to pursue a spin-off series with those characters or not.
