From the Summary: "The Fairness Doctrine was a policy of the Federal Communications Commission (FCC or Commission) that required broadcast licensees to cover issues of public importance and to do so in a fair manner. Issues of public importance were not limited to political campaigns. Nuclear plant construction, workers' rights, and other issues of focus for a particular community could gain the status of an issue that broadcasters were required to cover. Therefore, the Fairness Doctrine was distinct from the so-called 'equal time' rule, which requires broadcasters to grant equal time to qualified candidates for public office, because the Fairness Doctrine applied to a much broader range of topics. In 1987, after a period of study, the FCC repealed the Fairness Doctrine. The FCC found that the doctrine likely violated the free speech rights of broadcasters, led to less speech about issues of public importance over broadcast airwaves, and was no longer required because of the increase in competition among mass media. The repeal of the doctrine did not end the debate among lawmakers, scholars, and others about its constitutionality and impact on the availability of diverse information to the public. […] Any attempt to reinstate the Fairness Doctrine likely would be met with a constitutional challenge. Those opposing the doctrine would argue that it violates their First Amendment rights. In 1969, the Supreme Court upheld the constitutionality of the Fairness Doctrine, but applied a lower standard of scrutiny to the First Amendment rights of broadcasters than it applies to other media. Since that decision, the Supreme Court's reasoning for applying a lower constitutional standard to broadcasters' speech has been questioned."
