After all the memorial specials and colleague soundbites, it's still business over at ABC. It's been just one week since Peter Jennings' death and already ABC News prez David Westin has pulled his name from the network's World News Tonight.

But that doesn't mean they're any closer to naming a permanent successor, so Charlie Gibson and Elizabeth Vargas will continue to fill in.

Meanwhile, CBS's Les Moonves is also taking his time in naming the next host of CBS Evening News, leaving interim anchor Bob Schieffer in place. Only NBC had a transition plan in place, but it turns out that viewers don't care who's reading the news, as ratings are staying the same, emphasizing a point we made in early July: It doesn't matter which white guy sits in the chair.
