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:

The 2012 London Games will be Bob Costas’ 10th for NBC and his ninth as primetime host. After serving as late night host in 1988 from Seoul, South Korea, Costas earned acclaim for his work as primetime host from Barcelona, Atlanta, Sydney, Salt Lake City, Athens, Torino, Beijing and Vancouver. Costas, who has the longest tenure of the network’s sports commentators, joined NBC in 1980.

Al Michaels, one of the most renowned commentators of all-time and whose legendary “Do you believe in miracles? Yes!” call at the 1980 Lake Placid Winter Olympic Games 32 years ago stands as one of the most famous calls in sports history, will work his second straight Olympics for NBC, serving as host of NBC’s live weekend and weekday daytime coverage from London. Michaels was the daytime host at the Vancouver Winter Olympic Games in 2010, his first Olympic broadcast assignment in 22 years, when he covered hockey and hosted the Closing Ceremony at the 1988 Calgary Winter Olympics for ABC.

Carillo will also serve as an Olympic correspondent and provide a look into life in the United Kingdom through a collection of features done in her own inimitable style, similar to her acclaimed work during the Beijing and Vancouver Games. London is Carillo’s 11th Olympic Games and eighth for NBC.
