Medal winners will amp NBC in Beijing

Peacock to sport gold and silver analysts

NBC Sports will put a wealth of experience into the field — including input from 28 analysts who won a total of 42 medals in past Games — for its 3,600 hours of Olympic coverage next month.

The network is expected to announce today that there will be a total of 106 commentators across the 17 days of the Summer Olympics from Beijing. That's more than ever before, just as the network is putting together substantially more live coverage (2,900 hours) than ever before on TV and the Web.

Bob Costas will return for his eighth Olympics, his seventh as primetime anchor of coverage. The afternoon coverage on NBC will be hosted by Jim Lampley, who will be announcing his 14th Olympics, a record among broadcasters. Mary Carillo will host NBC's late-night coverage.

Telemundo's coverage will be hosted by Andres Cantor, Jessi Losada and Monica Noguera. CNBC and USA Network telecasts will be hosted by Alex Flanagan, along with Matt Vasgersian at USA. MSNBC anchors and hosts include Melissa Stark and Bill Patrick. Fred Roggin will host "Boxing in Beijing" on CNBC, while Lindsay Czarniak will host Oxygen's gymnastics coverage. (partialdiff)
