Singer Taylor Swift appears on Good Morning America on Oct. 22, 2012.
The morning news shows face some of the fiercest, most competitive time slots, and for the past 17 years, NBC’s Today show has been unbeatable. But after a controversial shake-up of its team, including the ouster of veteran anchor Ann Curry, Today tumbled from the top spot. A week after the end of NBC’s Olympic coverage, ABC’s Good Morning America overtook Today as the most watched morning news show, and its ratings have been fairly consistent ever since. While NBC continues to make changes to its on-air and executive teams, GMA has stayed with anchors George Stephanopolous and Robin Roberts, who was diagnosed with a blood and bone marrow disorder called MDS in June and has been on medical leave since August. In her place, viewers have tuned in to watch a parade of celebrity guest hosts, including Oprah, Katie Couric, Stephen Colbert and the cast of Modern Family — and they’ve stuck around, at least for now.
