Tom Bettag, who authored a recent advisory report for PBS on its news and public affairs initiative, has joined CNN Worldwide as senior e.p. for State of the Union with Candy Crowley and Reliable Sources, effective immediately, according to a CNN statement. PBS had asked Bettag last year to consider how public TV could reinvent its news offerings, and Bettag spent time meeting with executives in both pubTV and radio news units (Current, May 11 and 26, 2009.)
