Ads to pop up in Facebook news feeds

Facebook has confirmed that from next year advertisements will pop up in users' news feeds, reports said, citing a Facebook spokeswoman.

Facebook hopes to show people one sponsored story in their news feeds per day and the story will be clearly labeled, the spokesperson was quoted as saying.

Facebook's sponsored stories were introduced earlier this year, the reports said. "We wanted to give a way for application developers, page owners, place owners to be able to promote their content that's as core to the user experience as the news feed, and I think with Sponsored Stories we've created that," Facebook said at the time, reports said.
