Rebuilding a network is a slow, brick-by-brick process. It's not just creating a hit show - it's building shows to back up that hit show; it's creating an identity of success so that people want their shows on your network.

I take great pride in all the tremendous success we've enjoyed at CBS. And the good news is that I feel even more enthusiastic about what my terrific team and I will accomplish going forward.

I understand why creative people like dark, but American audiences dont like dark. They like story. They do not respond to nervous breakdowns and unhappy episodes that lead nowhere. They like their characters to be a part of the action. They like strength, not weakness, a chance to work out any dilemma.

We think wireless is going to grow tremendously. Do I think people are going to watch an episode of 'Survivor' on a 2-inch television set? I doubt it. But I do think somebody's going to go to a grocery store in the middle of a football game and watch that game.

CBS is proud to have been the home of David Letterman since 1993. He is truly one of the great talents of our time, and we hope things work out.

The stories about broadcast dying or it being overtaken by cable have stopped. Same goes for the stories about the Internet hurting our business.

Broadcasting for advertisers is still the best game in town, and they know it. Look, I admire a lot of the shows on cable. I think 'Mad Men' is wonderful. I think 'Breaking Bad' is wonderful. But let's remember they're about one-tenth the audience of NCIS.
