Television Shows Sell Books
The New York Times reports Comedy Central's Daily Show with Jon Stewart and the Colbert Report are among the most effective broadcast sales boosters for books. The two shows are on a par with 60 Minutes, Imus in the Morning, Larry King Live and Oprah.
The shows have ratings of 1.6 million and 1.2 million viewers respectively. Martha K. Levin of the Free Press called them "the television equivalent of NPR. You have a very savvy, interested audience who are book buyers, people who do go into bookstores, people who are actually interested in books."
