“Many producers and writers have maintained that a concentration of media ownership has led to a decrease in diverse and experimental television and that the new rules would make the situation worse because fewer outlets would be available and open to creative program ideas. The executives who supported the looser regulations said those arguments were ridiculous at a time when the average household receives about 100 channels of television. They also said good ideas would always be welcomed in a business desperate for hits. In a sense, the F.C.C.’s decision reignited a battle that goes back at least a decade.”
