Outbrain is the source of the "from around the web" advertising links at the bottom of news articles. They're generally just ads for diet pills and the like, disguised as other news stories.
Other similar vendors of the same kind of service are Taboola and Lockerdome.
Outbrain is one of the ad companies that creates the ads that blend in with the article recommendations that appear at the bottom of the article. They often use misleading photo/headline combinations. It really undercuts the credibility of the organizations that use it and contributes to an a culture of distrust towards the media.
