GM spends $40M on its Facebook presence and only 10M actually goes to Facebook.
Adam Rifkin stashed this in Facebook!
GM is going to stop advertising on Facebook:
General Motors plans to stop advertising on Facebook after the auto maker's executives determined their paid ads had little impact on consumers' car purchases, people familiar with the matter said.
Ouch, bad timing.
"GM's skepticism about Facebook is not due to a skepticism about digital advertising overall. GM spends about $300 million a year on digital brand advertising -- just not on Facebook." http://www.businessinsider.com/attention-facebook-investors-this-gm-ad-cancellation-is-big-bad-news-2012-5
