Postman

Postman, in the last paragraph of chapter 11, makes the distinction between the Age of Exposition and the Age of Show Business. He explains that now, in the Age of Show Business, as a result of entertainment, we laugh at things we do not understand, and we laugh at things that have no context and teach us nothing. In the Age of Exposition, people were entertained in their learning, while today we are not, and it negatively effects our intelligence and literacy. The example in the last paragraph referring to our laughter relates perfectly to Postman's premise that he has argued throughout the book: our entertainment is free of logic, and our obsession with entertainment is antagonistically impacting the attention span and acuity of our society today.
