What is the name of the building where the interior scenes of 30 Rock were filmed?

The interior scenes of 30 Rock were filmed mainly at Silvercup Studios in Long Island City, Queens, New York. The studio provided the controlled soundstage space needed for the sitcom’s offices, hallways, control rooms, and other recurring sets.

The show itself is set inside the fictional headquarters of NBC, with its title referring to 30 Rockefeller Plaza in Manhattan. That real building supplied the story’s setting and inspiration, but it was not the primary location for interior filming. This is why 30 Rockefeller Plaza is a tempting but incorrect choice.

Most episodes used a single-camera production style and were filmed in New York. Two live episodes were exceptions: those were staged at Studio 8H inside 30 Rockefeller Plaza, the famous home of Saturday Night Live. Silvercup Studios therefore remains the canonical answer for the ordinary interior production location, while Studio 8H applies only to those special live broadcasts.
