As "Today" struggles with losing its morning dominance to ABC’s "Good Morning America," NBCUniversal has tapped a new executive to take over ad sales for the NBC show, reports Jon Lafayette at B&C.

David Barrington, a vice president at NBC News Group Sales, is now in charge of selling airtime on "Today," along with other top NBC News shows such as "NBC Nightly News," the story says. He had been a top sales exec for MSNBC.

Barrington switched jobs with NBC News Group ad sales VP Tom Stevens, who will move to selling MSNBC ad time, the story says.

Lafayette notes: "’Today’ was the top morning news show for 16 years, winning the ratings race every week. But so far this season, ‘Good Morning America’ is leading ‘Today’ in adults 25-54, the key demo for ad sales for most news programming. ABC says its lead over ‘Today’ is the biggest in more than 21 years."
