ABC News Shuffles Executive Ranks
ABC News is shuffling its executive ranks in the wake of James Goldston's promotion in April to president of the news division.
Tom Cibrowski, who has been guiding Good Morning America as senior executive producer since 2012, is being promoted to senior vp news programs, news gathering and special events. The post effectively makes him Goldston's No. 2.
In an email to ABC News staffers, Goldston characterized Cibrowksi as "a true leader."
"For many years Tom has been a true leader at ABC News," wrote Goldston. "Tom and I served side by side in the trenches at GMA, and I have witnessed countless times his uncanny news sense, his tremendous command of breaking news and his absolute mastery in the control room."
Michael Corn, the executive producer of World News with Diane Sawyer, will replace Cibrowski at GMA. And Almin Karamehmedovic, who has been running Nightline for several years, becomes executive producer of World News with David Muir when Muir takes over the broadcast after the Labor Day holiday. For the time being, Karamehmedovic will continue to lead Nightline.
In praising Corn, Goldston noted World News' recent winning streak in the 25-54 demographic over NBC's Nightly News with Brian Williams, the longtime evening news leader.
"Michael leaves World News as the program draws its biggest audience in five years and has just won back-to-back sweeps victories in [the demo] for the first time in seven years. He has steadfastly carried on its greatest traditions and unwavering commitment to breaking news while keeping the broadcast fresh and relevant for our growing audience."
The changes have been expected for some time and were set in motion when Disney CEO Bob Iger last March tapped former ABC News president Ben Sherwood to lead the Disney/ABC Television Group. ABC News staffers threw Sherwood and his family a going away party last week in New York.
