Today we explore what we can say on the air. Are radio and television stations allowed to air their opinions in addition to the news? From 1949-1987 all broadcast media was beholden to the Fairness Doctrine; a law that enforced impartiality and civil discourse. So why did we have this law? How did it work? Why did it end?
