This Week is an American Sunday morning political affairs program from ABC News. The program is initially aired at 9:00 a.m. Eastern Time (following weekend morning newscasts on most ABC stations in large and mid-sized markets), although many stations air the program at a later slot, especially those in other time zones. David Brinkley was the original host from 1981 to 1996. Sam Donaldson and Cokie Roberts were the co-hosts from 1996 to 2002. Then, George Stephanopoulos anchored the program from 2002 to 2010. Christiane Amanpour was the anchor of the program from 2010 to 2011, and since 2012, George Stephanopoulos began his 2nd stint as host, and in 2016, Martha Raddatz became co-anchor of the program in an alternating basic.
