of Good Morning America. ABC News Senior White House Correspondent Jake Tapper served as the interim anchor from March to July 2010. On April 20, 2008, production of This Week relocated to the Newseum in Washington, D.C., in a studio that overlooks the U.S. Capitol. In addition, the program began broadcasting in high definition, becoming the first Sunday morning talk show to broadcast in HD. Following the transition, the program discontinued the segments Images and Voices. ABC and This Week moved out of the Newseum in 2013 due to infrequent use of the studio and other facilities, with the former studio later being used for the Washington bureau of cable news channel Al Jazeera America. Christiane Amanpour, a longtime world affairs correspondent at CNN, began as the program's host on August 1, 2010. During her first two months as host, the ratings for This Week reached their lowest point since 2003. In December 2011, it was announced that Amanpour would step down as anchor of the program, while returning to CNN in turn. On January 5, 2012, ABC News announced that Stephanopoulos would return as the host of This Week. With the return of Stephanopolous as moderator, the program began using former Good Morning America and World News Tonight anchor Charles Gibson to perform the voice-over heard during the opening of each broadcast; this lasted until 2014. In 2016, Martha Raddatz was named co-anchor of This Week, alternating each weekend with Stephanopoulos. Ratings In February 2009, the ratings gap between Meet the Press and its competitors – This Week and CBS' Face the Nation – began closing. Meet the Press posted its lowest ratings since NBC News correspondent David Gregory became moderator in early February of that year, with the February 1 telecast averaging just 3.9 million viewers. Face the Nation averaged 3.33 million total viewers, while This Week came in just behind with 3.32 million. This Week beat Meet the Press on January 11, when George Stephanopoulos interviewed President-Elect Barack Obama.
