NBC Olympics London CoverageOK maybe it only seems that way, but NBC said today that a record 115 commentators are set for the network’s planned 5,535 hours of Olympics coverage across its properties. The group is led by primetime host Bob Costas, working his 10th Olympics and ninth with NBC. NBC Olympics president Gary Zenkel said yesterday that there will be 3000 NBC cast and crew at the Olympic Broadcast Center by the time of the London Games’ Opening Ceremony on July 27. The commentators — including everyone in the NBCUniversal stable from Ryan Seacrest to Jimmy Fallon — will be broadcasting to an estimated 200 million viewers over the games’ 17 days. Here’s a list of the hosts, followed by a sport-by-sport breakdown of who’s covering what:
