A "Series Premiere" refers to the first episode of a new television series. It introduces the main characters, setting, and storyline, setting the tone for the episodes to follow. This initial episode is crucial for capturing the audience's interest and establishing the show's premise. Typically, a series premiere is heavily promoted to attract viewers and generate buzz. Networks often schedule it during prime time to maximize viewership. Successful premieres can lead to higher ratings and the potential for the series to continue for multiple seasons, as seen with popular shows like Game of Thrones and Stranger Things.
