The Fairness Doctrine had a very limited influence on the media in general. It's power has been vastly over stated as of the last 15 years.

It was only applicable to broadcast media, and rarely enforced. Nearly all of the enforcement was on behalf of private individuals wanting free airtime to respond to negative new stories about them.

In my opinion it's a very bad idea to want political appointees to decide when an issue hasn't been given fair news coverage. The very idea that there is only 2 sides to an issue reinforces the two party system that has made media so biased in the first place
