There's a couple of computer tech channels and game channels that are out of LA that I occasionally watch, and there's "Geek and Sundry" which is the sci-fi/fantasy fandom channel that's also out of LA. I guess maybe I've just watched too much of them.
The other reason I asked was because it seemed odd that the gaming and tech channels would be based in LA as most of the tech (and at one time most of the gaming industry) was based up here in the Bay Area.
SciShow is out of Kansas, and there's various car channels out of Texas, CA, UK, and NY and AUS.
I guess it was just me. Thanks for the replies.
