Twitter and NBC are set to team up to provide an official hub page for the London Olympics, with the microblogging service serving as an "official narrator" of the Games. The Wall Street Journal reports that tweets from athletes, fans, and TV personalities will be curated and hosted online on a page that NBC will heavily promote throughout its broadcasts. Neither party is paying for the privilege, but Twitter reportedly sees it as a golden opportunity to expand its audience beyond the current 140 million monthly users, with vice president of media Chloe Sladden calling it "a way for new users to sample Twitter." NBC, meanwhile, has already made social media a big part of its Olympics coverage by previously announcing tie-ins with Facebook, as well as live streaming apps for iOS and Android.
