2003 was a very different era, it was pre-HD and not like today where the studios, cameras and control room are much more advanced. Kate Snow was in a tiny booth to do the NBC Nightly News updates for other timezones, while MSNBC was broadcasting from a dimly lit newsroom. When I checked Fox News Channel, who's across the street from 30 Rock, they were doing their broadcast from Los Angeles. Meanwhile on WABC Wheel of Fortune was airing with a bunch of technical issues, the bottom quarter was on the top of the screen and the top 3/4's were at the bottom of the screen.
That's not from WNJU's main studio. They were doing their own 11pm newscast at the same time from their main studio.
