Facebook hires Google exec as new COO

Facebook has raided Google to hire a new chief operating officer, providing the popular online social network with more seasoned management and advertising savvy as it strives to make more money without alienating its audience, an Associated Press report said.

Sheryl Sandberg's defection from Google represents a coup for Facebook just three months after it suffered a humiliating setback in its effort to inject more commercialism into its fun-loving web site, the Associated Press report said.

As Google's vice president of global online sales and operations for the past six years, Sandberg helped build the internet search leader into one of the world's most prized companies, the report said.

She also helped set up Google.org, the Mountain View-based company's philanthropic arm.

Before joining Google, she served as the US Treasury Department's chief of staff during the Clinton administration.
