Bob Costas has signed a new, multi-year contract with NBC Sports. Costas, a pillar at the Peacock Network for more than two decades, will continue to host NBC's Olympic coverage and also take on additional sports and entertainment assignments. "It's a perfect combination of events and a schedule that works professionally and personally," said the venerable anchor, who also hosts HBO's On the Record and Inside the NFL. "I couldn't be happier that we were able to work it out."
