This article includes a list of hosts and commentators of the Olympic Games on NBC.
Source (please note that the paragraph containing the anchors for the 2008 Olympics was accidentally copied and pasted into the capsule for the 2010 Olympics):
(*) Though the United States boycotted these games, NBC held the rights to the Moscow Olympics, and the number of hours broadcast were reduced from 100+ hours to little more than three. The host for the two-hour wrap-up show was Bryant Gumbel, who was scheduled to be the main prime-time host. Therefore, he is given credit for being the anchor. Among those who were also supposed to have prominent roles in NBC's 1980 Moscow coverage were Donna DeVarona, Dick Enberg, Joe Garagiola, Merle Harmon, Charlie Jones, Bruce Jenner, David Letterman, and O. J. Simpson.
Another of NBC's hosts is Jim Lampley. Lampley has served as late-night host in 1992, 1996 and 2006. He was the daytime host in 2004, 2006 and 2008. During 2000 and 2002, he hosted cable coverage. The Beijing Games were his 14th Olympic assignment (including work for ABC, CBS and TNT), more than for any other commentator.
Al Michaels was weekday and weekend host of the 2010 Winter Olympics. This marked his first Olympic assignment since the 1988 Winter Olympics, which was the last to date aired on Michaels' long-time employer ABC Sports.
Hannah Storm also hosted four Olympics (late-night: 1992 and 1996, daytime: 2000 and 2002) for NBC. She left NBC for CBS News in 2002, then moved to ESPN in 2008; she began her new assignment as SportsCenter anchor on the first weekday of the Beijing Games (August 11).
Pat O'Brien anchored coverage of the 2002 Winter Olympics from the Medals Plaza in Salt Lake City.
Due to an eye infection, Costas was replaced by Matt Lauer for the Primetime and Late Night telecasts on February 11, 12, and 13th, 2014. Meredith Viera took over the Prime Time duties from Lauer due to Costas' prolonged illness for February 14 and 15. Matt Lauer was the replacement for February 16. Bob Costas returned on February 17 as the anchor for the rest of the Olympics.
For the 2014 Summer Youth Olympics in Nanjing, China, limited tape-delayed coverage aired on NBC, NBCSN, and Universal Sports, with 54.5 total hours of coverage airing - 24.5 hours on NBC and NBCSN, and the remaining 30 on Universal Sports. Josh Elliott was listed as a studio host, although for the NBCSN broadcasts, the play-by-play announcers for each sport tossed to commercial breaks and pre-taped segments.
Bob Costas hosted the August 18, 2016 late-night show from Rio, as the outdoor set at Copacabana Beach, where Ryan Seacrest was based for the Rio Games, had lost power, and it could not be restored in time.
