Zynga can also elect not to use Facebook Payments as the way for users to buy virtual goods, and it can also opt not to display ads served by Facebook.

Former NBC executive Zucker to lead CNN CNN made official its decision to install Jeff Zucker, the former chief executive of NBC, as the new president of CNN Worldwide.
