Yesterday the U.S. Department of Justice sued Apple and five major publishers on antitrust grounds, alleging they fixed prices of e-books throughout 2010. According to the Department, consumers may have been paying as much as $5 too much for e-books. Three of the publishers have settled. Joe Nocera is an Op-Ed Columnist at the New York Times, and joins us to talk about how book pricing works, and what yesterday’s legal actions mean for the future pricing of e-books.
