ABC News is reshuffling its deck of top executives.

Tom Cibrowski, who helped lead “Good Morning America” to steal first place among morning shows from NBC’s “Today,” has been promoted to senior vice president, ABC News Programs, News Gathering and Special Events.  Cibrowski has worked at “GMA” for the past 13 years and now will report to ABC News President James Goldston, helping to drive more collaboration across the division’s various programs.

“From the Boston Marathon bombing to Hurricane Sandy, he was the mastermind behind our hard-charging coverage of breaking news at GMA,” said Goldston.  “He’ll lead ABC News into the future, driving all our platforms to tell even more great stories, cover the biggest events and do the most important journalism. For many years, Tom has been a great leader at ABC News and a true friend.  I know that he will take us to even greater heights.”

Meanwhile, Michael Corn, who has been executive producer of “World News” for the last three years as it as anchored by Diane Sawyer, will take over as executive producer of “Good Morning America.” Corn has previous experience with the show, having spent a decade there as a producer.

Added Goldson, “As Michael brings his considerable talents back to Good Morning America, I’m confident that he and the GMA team will lead the show in innovative new directions in the future.”

Almin Karamehmedovic, executive producer of “Nightline,” will take over as executive producer at “World News” as David Muir takes the anchor chair. He is expected to continue to oversee “Nightline” on an interim basis.

“I am confident Almin and David Muir will make a formidable team. Not only do they have a great history of working together, but they also share a similar immersive, urgent, all-access storytelling style,” said Goldson.  “‘GMA,’ ‘World News’ and ‘Nightline,’ collectively, have added well over a million new viewers in mornings, evenings and late night in the last two years, thanks in many ways to the leadership of Tom, Michael and Almin.    Most importantly, all three share my firm belief that we have an incredible opportunity to serve our audience with news that informs, inspires and empowers them.’
