pilot problem

A television pilot (also known as a pilot or a pilot episode and sometimes marketed as a tele-movie) in United Kingdom, Ireland and United States television, is a standalone episode of a television series that is used to sell a show to a television network or other distributor. A pilot is created to be a testing ground to gauge whether a series will be successful. It is, therefore, a test episode for the intended television series, an early step in the series development, much like pilot studies serve as precursors to the start of larger activity.
A successful pilot may be used as the series premiere of a new show, or as a later episode, though some are never aired at all. Some series are commissioned straight-to-series without a pilot (although an increasing number of such series have their first episodes titled "Pilot"). On some occasions, pilots that were not ordered to series may also be broadcast as a standalone television film or special.
A "backdoor pilot" is an episode of an existing series that heavily features supporting characters or guest stars in previously unseen roles. Its purpose is to introduce the characters to an audience before the creators decide on whether or not they intend to pursue a spin-off series with those characters.
Television networks use pilots to determine whether an entertaining concept can be successfully realized and whether the expense of additional episodes is justified. Variety estimates that only a little over a quarter of all pilots made for American television proceed to the series stage.
