Question: The pilot episode for the television series about a five-person team who use their skills to fight corporate and governmental injustices originally aired on what date?
Context: Phoebe Halliwell is a fictional character from the American television series "Charmed", played by Alyssa Milano from October 7, 1998 until May 21, 2006.  The character was originally played by Lori Rom in the unaired pilot episode.  However, Rom quit the series, and a new pilot was filmed with Milano in the role of Phoebe.  The character was created by Constance M. Burge and is based on Burge herself.  Phoebe is introduced into "Charmed" as the youngest sister to Prue (Shannen Doherty) and Piper Halliwell (Holly Marie Combs).  She is one of the original featured leads and, more specifically, a Charmed One – one of the most powerful witches of all time.  Phoebe initially possesses the power of premonition, which enables her to see into the future and the past.  To make up for initially only having a passive power, Phoebe develops martial arts skills in order to better assist her sisters when they fight evil beings.  As the series progresses, she also gains the active powers of levitation and empathy. 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.
