A showrunner is the person responsible for the overall creative direction and management of a television series. They oversee the writing, production, and often the casting of the show, ensuring that the vision is consistent throughout the episodes. Showrunners typically have a strong background in writing and may have previously worked as writers or producers on other shows. In addition to creative duties, showrunners handle logistical aspects, such as budgets and schedules. They often collaborate with networks and studios to align the show's goals with audience expectations. Successful showrunners, like Shonda Rhimes or David Benioff, are known for their ability to create compelling narratives and lead large teams.
