2. Flagship (broadcasting)In broadcasting, a flagship (also known as a flagship station) is the broadcast which originates a television network, or a particular radio show or TV show, primarily in the United States and Canada. This includes both direct network feeds and broadcast syndication, but generally not backhauls. Not all networks or shows have a flagship station, as some originate from a dedicated radio studio or TV studio.
