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. The demise of this FCC rule has been considered as a contributing factor for the rising level of party polarization in the United States.[2][3]
The Fairness Doctrine deals with discussion of controversial issues, while the Equal Time rule deals only with political candidates.
