Bob Walker, President and General Manager of WXIA since 1996 has left. He was named an Executive Vice President at The Weather Channel yesterday. It is just the beginning of a changes at WXIA. Ellen Crooke the News Director at WXIA is also rumored to be on her way out. Ratings have continued to dive, down 40% since 2007. She has surrounded herself with people who she hired and were loyal to her and turned out numerous long time staffers. That would have been fine if ratings improved or the on-air product at least improved. With ratings at all time lows, ad revenue in the dump, and not having received any olympic bounce, the revolt has started. Look for a new WXIA GM and then a new News Director in the next 3-6 months.
