Since I have digital cable and live on the west coast of Canada, strangely enough, I get American network feeds from Detroit and Rochester, three hours ahead. I watch three full-length shows on FOX (WUHF) and ABC (WXYZ), two full-lengths on CBS (WWJ), and one full-length and up to two half-hours on NBC (WDIV) . I also watch one full-length on UPN (KSTW), but that's in my time zone.
So by default, I'd say FOX and ABC. FOX has the shows I like better, but their scheduling and hiatuses (*cough* Prison Break) drive me nuts. So that about evens the two out.
As much as I wish it wasn't so, Canadian channels and shows largely suck. Muchmusic doesn't count (although it does kinda suck these days), and CBC, CTV, and Global I only touch for news or for local playings of shows I couldn't catch three hours beforehand.
But yikes. 11 hours of primetime TV per week. Not including the miscellaneous other times...
FOX probably has the most shows I watch, but I'm not big on television. The majority of the shows I watch are purchased in boxsets and watched on the personal DVD player I got for Christmas. :D
well, my favorite networks (i.e. the ones I watch most) are:
-Fuse (for music videos)
-G4TV (for X-play and Attack of the show)
-Discovery (for Mythbusters and Dirty Jobs)
-Fox (for House and 24)
-USA (for Law and Order and House)
-Nicktoons (for Invader Zim)
-Spike TV- (for CSI)
