Facebook To Introduce Sponsored Stories For News Feeds

Josh Constine:

The ads will be marked “Sponsored” and a rate limit will ensure users see no more than 1 Sponsored Story in the news feed per day. They’ll only feature stories about friends or Pages that users already like. Users won’t be able to opt out of seeing Sponsored Stories in the news feed or having their activity used in them, but they will be able to ‘x’ out individual ads.

Well, it looks like it's starting.
