It’s no coincidence that Facebook announced the formation of its own political action committee the same week it unveiled a raft of new features and third-party content integrations at the f8 conference. Facebook is going to be collecting vast amounts of new information about its users, which is going to raise new questions about how it uses that data, currently a very hot topic on Capitol Hill. The PAC, in fact, is only the latest move by Facebook to step up its game in Washington as it comes under greater scrutiny from regulators and Congress. It opened a lobbying shop in 2009 and doubled spending in 2011 over 2010. Apart from privacy issues, expect to see Google to try to shift some of the anti-trust spotlight off itself by pointing fingers at Facebook’s growing ambitions in the media space, if only to make Facebook play some defense.
