Gave AT&T a monopoly on the wires Forced to sell BCA to RCA At&T group would become NBC red RCA Group would become NBC blue

11 Radio Act 1927 Stated that radio stations do not own signals and instead licensed them from the government As long as they served a public interest Created the FRC which would later become the FCC

12 Golden Age of Radio Early 1920’s to 1950’s Radio wasn’t portable
Characterized by the dominance of radio shows Birth of the soap opera Called soap operas because sponsored by soap companies

FM was a better and clearer signal David Sarnoff hindered FM due to the dominance of RCA’s AM networks Armstrong tried to establish FM on his own Between 1946 and 1949 there went from 48 to 700 FM Stations FCC moved the FM band making many FM radios obsolete FM would not become the dominant format until 1979

16 Format Radio Before format radio, DJs controlled the content
In format radio, management controls the playlists Rotation means playing the top songs many times per day Top 40 format gets its name from the number of discs a jukebox held Came to mean top 40 hits

Record companies pay stations to play songs Station has to run a disclaimer Like an infomercial
