In the United States, the term "flagship station" may also be used in the broadcasting industry to refer to a station which is co-located with the headquarters of its station group and considered the company's most important station (such a station may or may not be affiliated with one of the major networks). For example, WDIV-TV in Detroit, affiliated with NBC, is the flagship station of Graham Media Group; and WGN-TV in Chicago was the flagship station of Tribune Broadcasting until it was purchased by Nexstar Media Group in 2019.
