General Motors, the world’s largest automaker and third biggest advertiser in the U.S., plans to stop advertising on Facebook, The Wall Street Journal reported on Tuesday. After meeting with Facebook managers to address concerns, the company’s marketing executives were left unconvinced of the effectiveness of the site’s advertising methods, claiming its paid ads had little impact on consumers. GM will thus pull its $10 million ad spend, although the automaker will continue to use the social networking site to display free content on its own Facebook page. GM is only skeptical about Facebook, and not about digital advertising as a whole; the company spends almost $300 million each year on digital brand advertising. The news comes at a bad time for Mark Zuckerberg and company, who are on the verge of their initial public offering.
