What argument does Minow make in his speech?

Television executives have a responsibility to provide better programming.

Explanation:

So this is all based off the assumption that you're talking about an excerpt from television and public interest but, Television executives have a responsibility to provide better programming. This is the main claim that Minow makes in the essay. The essay is mainly addressed at television executives who can make choices about TV programs. At the beginning of the text, the author discusses how television is mostly a "vast wasteland." He tells us that most TV is boring. He also tells us that this affects children in particular, who spend many hours a day watching TV. What Minow wants to prove is that executives have a responsibility to provide better programming.
