A pilot episode is the first episode of a television series, created to showcase the show's concept, characters, and overall tone. It serves as a prototype to attract networks or streaming platforms, helping them decide whether to order more episodes. Typically, a pilot episode introduces the main characters and sets up the central conflict or theme of the series. If successful, it leads to the production of a full season, allowing viewers to explore the story further. Many popular shows, like Friends or Breaking Bad, began with a pilot that captured the audience's interest.
