This image released by NBC shows Yahoo CEO Marissa Mayer appearing on NBC News' "Today" show, Wednesday, Feb. 20, 2013 in New York to introduce the website's redesign. Yahoo is renovating the main entry into its website in an effort to get people to visit more frequently and linger for longer periods of time. The long-awaited makeover of Yahoo.com's home page is the most notable change to the website since the Internet company hired Marissa Mayer as its CEO seven months ago. The new look will start to gradually roll out in the U.S early Wednesday. (AP Photo/NBC Peter Kramer/NBC/NBC NewsWire) less
