There seem to be a lot of spin off shows on everything.
Right now and the last year its Alaska shows.
There was Out of Alaska a few years ago or the Alaska Experiment the yr before that, then Palins Alaska, before that IRT, then Gold Rush, then the Alaska State trooper show i have seen on some channel, The deadliest Catch, there is the weather channel Coastgaurd Alaska show, Hook line and Sisters (which i cant find the reruns as i missed the preview with my DVR)now bearing sea gold!! Its hard to keep up with um all. I have seen it all except state troopers and ALaska CG, HLS, and of course bearing sea gold as it premires this friday after goldrush. Every episode of um all.
EDIT: Forgot the show about the Kiltcher Family (Jewel the singers family) Alaska: the last Frontier (i think thats what its called.) This show rocks!!
Theen think of pawn stars, there is or was pawn queens, now theres cajun pawn stars. These shows i beleive spured the auction shows which is auction stars i think and some other one as well.
They make it hard for us that like these shows to keep up there so many its hard to watch um all, as i like pretty much anything that gets put out, but i guess im the target audience. Male well educated family man, 25-45 demographic.
