It's called targeted advertising, it looks for key words in the article and adds advertising relevant to those words. Hence if Heathrow is used repeatedly you're going to get loads of adverts for it.

Can someone please explain why this story was promoted, because AFAIK it breaks the rule on reposts and furthermore, is a sectarian/factious bash against Climate Camp. I thought the purpose of the promoted newsfeed was so I didn't have to read this and the conspiracy loons? As to the actual story being represented here, go do some action against the Guardian, don't just complain that someone else's action got used by a commercial site. Then maybe you'll have something to make clicking "publish your news" worth your time and mine.

" Because there are still some climate activists around who think that they can advance their campaign by giving their stories to the mainstream media."

Unless indymedia has found a way to reach the same number of people as the mainstream media, then my guess is they have more chance of advancing their campaign via MSM, than on a relatively unknown 'radical' news site.
