New host of "This Week" is ... Christiane Amanpour?

It’s an interesting choice on a number of levels. The most obvious being that ABC felt it had to go outside the network to find someone for the job. Over the past few months the network has experimented with a number of guest hosts all from within ABC’s family: Jake Tapper, Terry Moran, Barbara Walters. Early on many viewed Moran as the likely successor to Stephanopoulos, who left to take over Diane Sawyer’s job at Good Morning America. Lately, however, Jake Tapper has appeared to be the crowd favorite. Only very recently did Amanpour’s name pop up as a possibility.
