General Motors, one of the nation's largest advertisers, says it will no longer advertise on the social media site Facebook. GM will officially pull paid advertising from Facebook on Wednesday.

GM says it decided to halt all Facebook advertising efforts after research indicated marketing efforts on the social media site were ineffective. However, GM will continue to maintain a presence on the Web site.

"We regularly review our overall media spend and make adjustments as needed," GM spokesman Greg Martin told The Detroit News. "This happens as a regular course of business and it's not unusual for us to move our spending around various media outlets "" especially with the growth of multiple social and digital media outlets. In terms of Facebook specifically, while we currently do not plan to continue with advertising, we remain committed to an aggressive content strategy through all of our products and brands, as it continues to be a very effective tool for engaging with our customers."

last year GM spent about $270 million on internet advertising, with $10 million of that going to Facebook ads.
