The British government and six major British companies, including cell phone giant Vodafone, have pulled advertising on the social-networking Web site Facebook.
According to News.com the advertisers have concerns about how their ads are displayed. Apparently they were appearing on the profile page of the far-right British National Party.
The problem is that ads pop up on Facebook pages on a rotating basis, giving companies limited say over where they are displayed. The UK government's Central Office of Information (COI) said it was seeking assurances that ads on social-networking Web sites would reach desired audiences.
It said it would not resume advertising until better safeguards were in place.
