Days before the start of broadcast network upfront presentations, television advertising sales veteran David Barrington is switching sides again.

Mr. Barrington, who was hired by media buyer MPG as executive VP, managing director of video investments in January, is expected to join NBC Universal in a senior role under President Mike Pilot and President for Network Sales Marianne Gambelli.

An NBC spokeswoman declined to comment and Mr. Barrington couldn't be reached for comment.

Before joining MPG, Mr. Barrington had been head of sales for MyNetworkTV.

With Mr. Barrington’s departure, MPG North America CEO Charlie Rutman will be in charge of the agency’s upfront negotiations.
