Once upon a time in The United States of America, the media broadcasts on the air belonged to the American public.
Then Congress became concerned that the monopoly audience control of the three main networks, NBC, ABC, and CBS, could misuse their broadcast licenses to set a biased public agenda. The Fairness Doctrine mandated broadcast networks devote time to contrasting views on issues of public importance. https://www.fcc.gov/
Should the FCC’s Fairness Doctrine be Reinstated?
The doctrine did not require equal time for opposing views but required that contrasting viewpoints be presented. The demise of this FCC rule has been cited as contributing to the rising level of party polarization in the United States.
