Facebook spent more than $1.3 million on lobbying efforts last year, passing the $1 million mark for the first time, according to disclosure documents.
In 2010, by contrast, Facebook spent less than $400,000.
And Facebook's fourth-quarter spending for last year was $440,000, up from $130,000 during the same period in 2010.
Facebook upped its advocacy efforts as scrutiny of its privacy policies increased. In recent years it has hired Joel Kaplan, a former deputy chief of staff for George W. Bush, and Marne Levine, former chief of staff to the White House's National Economic Council, among others.
The increase in spending, however, wasn't enough to catch up with Google, which spent about $3.7 million in the last months of 2011.
