The major broadcast television networks have something to celebrate. Each has at least one new prime-time entertainment series that's drawn at least 10 million viewers.This comes as cable networks like AMC are drawing comparable or better ratings with series like "Breaking Bad" and "The Walking Dead."But there's another important trend. The latest data show growing numbers of viewers watching shows on a delayed timeline through their video recorder or computer.Tonight, we look at the role of viewers, as seen by a pair of writers who have long chronicled the media business.Hari Sreenivasan has the latest conversation in our series on the future of TV.So far in this series, we have heard from a disrupter named Aereo and we have heard from one of the established players, Comcast.Today, for a perhaps 10,000-, 20,000-foot view, we're joined by Ken Auletta from The New Yorker and David Carr from The New York Times.So, is this period now a transformative time for the viewer when it comes to television?I think television is now going through what newspapers, magazines and book publishing, print world has gone through, the digital disruption.And that has a profound impact on the viewer, because the viewer today, because of technology, can watch what they want when they want to watch it and on what device they want to watch it for.The questions in the future become, will you have enough advertising or other revenue to sustain quality production?
