NBC was going to plunk down $25 million bucks for a new set for Jimmy Fallon and the Tonight Show, but then they remembered they are owned by Comcast.​

So that ain't happening. ​

Word is NBC spent seven months working on plans that called for the combining of Studios 6B and 8G and turning them into a megastudio for Fallon as well as a showy theater for NBCUniversal to screen movies. Including a balcony, the facility would have fit an audience of 400.

The project, though, recently was scrapped, says an insider, and now when Fallon becomes host of Tonight, he'll have to settle for a mere $5 million renovation of Studio 6B, where he currently hostsLate Night With Jimmy Fallon. The insider says Fallon and Lorne Michaels, who will take over as executive producer when Fallon replaces Jay Leno, are OK with the less ambitious plan.

Work is set to begin in the summer and take about six months; Fallon will move his current show to Studio 6A until Studio 6B's makeover is complete. When it's done, Studio 6B will have an entirely different infrastructure and look, and it will accommodate an audience of about 240, up from the current capacity of 189.
