1949: The Fairness Doctrine was a policy of the United States Federal Communications Commission (FCC) that required the holders of broadcast licenses to present controversial issues of public importance and to do so in a manner that was honest, equitable, and balanced
"The Fairness Doctrine had two basic elements: It required broadcasters to devote some of their airtime to discussing controversial matters of public interest, and to air contrasting views regarding those matters. Stations were given wide latitude as to how to provide contrasting views: It could be done through news segments, public affairs shows or editorials. The doctrine did not require equal time for opposing views but required that contrasting viewpoints be presented"
Interesting George Takei involvement.
