In Vancouver: Bob Costas

Bob Costas did Bob Costas (maudlin voiceovers, unexpectedly thorough reporting).

In Sochi: Andrew Siciliano

What RedZone did for your Sunday NFL experience, NBC hopes to replicate with Gold Zone, a streaming channel on NBCOlympics.com providing live look-ins to events as they happen, eight hours a day (7 am–3 pm ET). It'll even be hosted by Siciliano, who spent the last few months anchoring Red Zone for DirecTV. Beyond that, NBC will stream every event live online – as it did in Vancouver – and produce heaps of originally produced, digital-only programming available through its website and accompanying apps.
