“In the 41 years since my first Olympics, it’s staggering to me to be involved in a Games where we are producing 2,900 hours of live coverage -- especially from an Olympics half a world away,” NBC Sports and Olympics chairman Dick Ebersol said in a statement. “It’s more live coverage from a single Olympics than the total of all previous Summer Olympics combined. The enormity of what we’re doing just blows me away.”
