A television series is a set of episodes that are released over time and usually follow a specific storyline or theme. It is a program that airs in multiple parts, with each part being called an episode. Television series can be either scripted (with a predetermined plot) or unscripted (where the events unfold in real-time). They can also vary in length, from short-run shows of only a few episodes to long-running series that continue for several seasons. Some popular examples of television series include dramas like "Game of Thrones" and comedies such as "The Office."
