If you want to purchase a Sponsored Story on Facebook, you’d better do it fast
The social network will retire Sponsored Story advertisements beginning April 9, according to a blog post
Sponsored stories show when a user’s Facebook friend interacts with a sponsored Page, app or event. For example, if one of your Facebook friends Liked Nike’s Brand Page, and Nike chose to promote that interaction, you would see it as a Sponsored Story within your News Feed
Advertisers will be able to buy Sponsored Stories up until April 9, at which point all existing Sponsored Stories will transition into other ad formats. For example, a Sponsored Story highlighting a page Like will simply turn into a Page Like ad.
