A new Forrester study says Facebook, which grabbed over $4 billion in advertising revenues last year, is a cash sink for advertisers.

The Home Depot is taking steps to make amends for a racist tweet it sent from its official account on Nov. 7. The tweet, a promotion aligned with ESPN college football coverage, showed a photo of two African-Americans playing the drums along with a person wearing a gorilla mask and the caption: "Which drummer is not like the others?"

This Flickr site is a must for marketers who are either bored or looking for something wicked or at least immoderate to do with their CPGs for the Holidays. How about White Chocolate Pringles?
