NBS Studios Burbank CA.

Also located a few blocks from my hotel was NBC's Burbank studio.

In 2007, NBC reported that the studio will leave "beautiful downtown Burbank", the historic studio where Johnny Carson and Jay Leno taped "The Tonight Show" and Bob Hope taped his annual specials.
NBC is planning to sell the land (34 acres in all) and will reportedly relocate its facilities to a new, state-of-the-art facility planned for Universal City, just north of Universal Studios Hollywood, near the existing Red Line station. (Universal is owned by NBC.) The new headquarters (to be called "The West Coast News Headquarters") won't be finished until 2011, so NBC will probably lease back some of the studio space until their new facilities are ready for prime time.
"The Tonight Show", which will see Conan O'Brian become the new host in 2009, will reportedly move to Stage 1 at Universal Studios Hollywood.

The fortunes of the National Broadcasting Company (NBC) have always been closely tied to those of its parent company, Radio Corporation of America (RCA). Unlike CBS, which was formed as an independent programming enterprise, NBC came into existence as the subsidiary of an electronics manufacturer which saw programming as a form of marketing, an enticement to purchase radio and television receivers for the home. The power and influence of a national network aided RCA as it lobbied to see its technology adopted as the industry standard, particularly during the early years of television and in the battle over color television.
