There are a number of problems with the Fairness Doctrine in principle. The intent of it is that nobody monopolizes the then-scarce licensed broadcast stations. This is not a problem today, as TV and radio broadcast stations are abundant and also compete with the Internet and thousands of cable channels. A more reasonable attempt at such a law today might provide oversight on the licensure of individual TV and radio stations to ensure that new stations can be started up easily. I'm not convinced it is a real problem today except on PBS and NPR, which are taxpayer-funded and seemingly biased.
