Philadelphia radio broadcasting began in 1922, when the city's first officially licensed stations went on the air. Within a few years, what had begun as a small, experimental medium became a full-fledged craze as families listened to live news, sports, and entertainment for the first time. In 1932, the first building designed for radio broadcasting opened on Chestnut Street, coinciding with the golden age of radio that featured live orchestras, soap operas, and imaginative dramas. In the 1950s, a few stations began playing rock and roll, and Philadelphia became known as a city that not only produced hit music but also consistently broke new acts. By the 1970s, FM radio began to grab the majority of listeners, and once again Philadelphia stations were responsible for breaking new artists, such as Billy Joel and Bruce Springsteen.
