Reminds me of Neil Postman's "Amusing Ourselves to Death" (1985), in which he argues that TV as a medium is fundamentally incapable of producing anything other than entertainment. So things like news, political discussion, or any other type of educational programming can only exist on TV as a nutrition-less pantomime of the real thing.

Education, real education, can be made entertaining. Mythbusters and Connections (I believe it was called) both qualify. As do some historic documentaries.
