In contrast to other American cities, where it referred to a concentration of radio stores, in Los Angeles, Radio Row was understood in the 1940s and 1950s as the area around the intersection of Sunset Boulevard and Vine Street in Hollywood, where the broadcasting facilities of all four major radio networks were located. The last radio station to broadcast from a studio on Vine Street, KNX-AM, closed its Vine Street studio in 2005.[1]
