Facebook and NBC are expected to announce a partnership for the London Olympic Games, similar to its election deal with CNN. Facebook users will be reminded to watch NBC’s coverage, and NBC viewers will be reminded to join the conversation on Facebook. It lets both to earn more money from advertising. It's much different from Facebook’s Olympics deal with BBC. BBC will live stream Olympic events on Facebook. The BBC deal is better for Facebook because people will stay on Facebook to watch, rather than leaving to watch or splitting their attention between two screens.
