Two recent events have rocked the publishing world. First, The New York Times, which many regard as the newspaper of record in the U.S., said it would abandon the practice of providing free online content and start charging regular readers beginning in 2011. And second, Apple’s much-hyped tablet — the iPad — made its appearance. What implications will the Times’ decision have for newspaper publishers and other providers of free online content? How will the iPad re-define what a book means, as well as how it is produced, marketed and delivered? Peter S. Fader, a marketing professor at Wharton and co-director of the Wharton Interactive Media Initiative, and Stephen J. Kobrin, a management professor at Wharton and editor of Wharton School Publishing, weigh in on how these developments could reshape publishing.
