A television pilot (also known as a pilot or a pilot episode) 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.
