i think probably into NBC, i'm sure if you go onto the NBC site they might have information... hope that helps and GOOD LUCK!

Maybe you could also try Deedle-Dee productions or Reveille productions. I am not sure how the co-production between NBC and these production houses is constructed, as in who writes, who distributes, who does the day to day production, but I think I heard somewhere that the writers are in these companies, and not so much with NBC. Hope this helps. Good luck and keep writing!
