Nike #Breaking2 Twitter Live

With the final race time announced only hours in advance, Twitter built a never-been-done RSVP system — launched through First View around the world — to quickly scale awareness of the upcoming livestream. This new RSVP system delivered users a personalized reminder at the precise moment the livestream began. Twitter users around the world watched together — even into the early hours of the morning — as one runner, Eliud Kipchoge, crossed the finish line in the fastest marathon ever run.
