The Icons that Built America - Season 1, Episode 03: Shock Jocks

For decades, the radio world has been dominated by top-40 music, while the DJ is expected to simply shut up and play the next track. But in the 1970s, two maverick broadcasters take a different approach, challenging their bosses, the rules and polite society to help create a new genre: talk radio. One will launch an all-out war with his own station as he goes to shocking lengths in a bid to for the top spot in New York, while the other will launch a political revolution on the airwaves in an effort to save AM radio from extinction.
