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 its 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 also 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 and David Benioff, are known for creating popular series that resonate with viewers.
