 Well, the days of plausibly live Olympics coverage on NBC coming to an end. The network says Mike Tirico will host what are essentially two primetime Olympics telecasts, one in the afternoon with live events and the second that curates the day's best events for the U.S. primetime viewing hours. That's while Paris is sleeping. It's a nod to reality. NBC has been criticized over the years for holding back on showing live competition and instead delaying it and airing it online.
