A FIRST: Facebook's No. 2 executive, Sheryl Sandberg, has become the first woman on the social-networking company's board of directors. She is also the first Facebook executive other than founder and CEO Mark Zuckerberg on the board.
FROM GOOGLE: Sandberg, 42, was lured from Google in 2008 to become Facebook's chief operating officer. She has been largely responsible for building the company's advertising business and also often serves as Facebook's public face.
LITTLE CHANGE: Sandberg is already a highly influential executive at Facebook, which is unlikely to change with her board appointment.
