<human>: Katherine Anne Couric ( KURR-ik; born January 7, 1957) is an American journalist and author. She recently served as Yahoo! Global News Anchor. Couric has been a television host on all Big Three television networks in the United States, and in her early career was an Assignment Editor for CNN.

Couric was a special correspondent for ABC News, based in New York, a role she has incorporated into her talk show. Her first appearance on the network was a Sarah Jessica Parker interview on Nightline. Couric co-anchored coverage of the 10th anniversary of the September 11 attacks, alongside Diane Sawyer, Christiane Amanpour, Barbara Walters, Elizabeth Vargas, George Stephanopoulos, and Robin Roberts. Couric was hosting Today on NBC at the time of the attacks, and led CBS News's coverage of the 5th anniversary. Couric also guest co-hosted The View and Live! with Regis and Kelly. Couric interviewed Lady Gaga in primetime on Thanksgiving as part of A Very Gaga Thanksgiving. In November 2011, Couric hosted a special primetime ABC news program highlighting Regis Philbin's retirement, after Philbin's 25-year tenure at ABC.  Similar to colleague Barbara Walters, Couric anchors specials for the network and for the newsmagazine 20/20. While she contributes to the news program all throughout the year, in 2011, Couric created her newly annual special The Year with Katie Couric, which is a program that marks the end of the year and covers some of the biggest newsmakers and news events of that year. This is a collaboration with People magazine, which also reflects events in the world of news, sports, politics, and major headlines that helped shape the world. This is very similar to that of Walters's iconic Barbara Walters' 10 Most Fascinating People, a year end program that marks the end of the year and acknowledges the people that had the most impact on the year at hand with interviews on their perspective of the year. As part of the special, Couric interviews fellow members of the media that can provide some insight on some events that occurred.  From April 2 to 6, 2012, Couric substituted for co-anchor Robin Roberts on ABC's Good Morning America, her first stint at hosting a morning news show since leaving Today.
