"From a Media Ecology perspective, it is possible to examine television content as a function of the television medium itself. As a "one to many" medium, American television acts to dictate and reinforce acceptable social norms and behavior. The content of television seems to have fallen by accident into three distinct categories : entertainment, news and advertising. In fact, these broad categories of programming each stake out a different level of social behavior to manage and control."-R. Blechman
