Why 30 Rock (The Show) Exists

I just realized why "30 Rock" exists.

Tina Fey wanted to create a one-camera sitcom. She didn't want to do a family comedy, so she couldn't do something centered around the house. She doesn't have an office job, so she couldn't do a normal workplace comedy. She doesn't drink, so she couldn't do a bar-centric comedy. She isn't silly enough to try and remake "Friends," so she didn't place it in a coffee shop.

So she took what she knew - TV, and went with that.

How did I figure this out? I just went through the exact same process in my head.

(Though, of course, now I have to cross Backstage TV World off my list, too. Hmm... what else can I do?)
