Facebook and Zynga alter deal

  • Facebook and Zynga have altered an agreement that gave the games developer significant access to the social network's one billion users.

    Zynga is the developer behind Farmville, a game once mostly played on Facebook. At its peak, the game attracted 82 million players a month and figures suggest 80 percent of Zynga's revenue comes from Facebook users.

    Zynga will now have its own games platform but players will no longer be able to share their progress on Facebook.

    Zynga's share price dropped by 13 percent in after-hours trading following the news on Friday.

    The change is due to come into action from March 31, 2013 and will end Zynga's ability to promote its platform on Facebook.

    The move also means it will no longer be required to display Facebook advertising on its own website.
