But if they’re tuned in during prime time on NBC, very little of what they see will be happening live. Sochi is nine hours ahead of Eastern standard time, so as it has done in the past, NBC is relying on the tape delay to piece together each day’s highlights into a package for its evening audience. Select events will air live across NBC’s other networks, but the internet remains your only real choice for comprehensive live coverage — and NBC is perfectly happy with that. The time difference doesn’t allow for us to be live in prime time, said Mark Lazarus, NBC Sports Groups chairman, during a recent conference call discussing NBC’s plans.
