Today the cast and crew of 30 Rock took over the NY1 newsroom, and Pat Kiernan has done a terrific job of live-blogging and Twittering behind the scenes — including a note to his future self, saying, "Just had a nice chat with Alec Baldwin. Turns out he's a regular NY1 viewer. Must be nice next time there's a tabloid headline on In the Papers." Speaking of In the Papers, there was a missed opportunity for comedy gold by not turning over today's segment to Tracy Jordan.

While today's shoot doesn't mean we'll see the local news station get an NBC cameo (on air their studio will represent CNBC's newsroom) — Kiernan says, "Maybe they’ll write us in to an episode one day as the evil crosstown rival to NBC."
