Neil Postman examines the deep and broad effects of television culture on how we conduct our public affairs and how "entertainment values" have corrupted the way we think. As politics, news, religion, education, and commerce are less often expressed in the form of the printed word, they are rapidly being reshaped to suit television. Television is a visual medium whose images are most pleasurably apprehended when they are fast-moving and dynamic, so discourse on television has little tolerance for argument or explanation. Postman argues that public discourse is being converted from exposition to entertainment.
