I certainly can thank the Sci-Fi (before it became SyFy) channel for introducing me to the books.  I didn't have a big book store where I was going to college, and I didn't get to go to one much, so when I had time to read for pleasure it was from books worlds familiar to me, and I hadn't tried any new stuff in a while.  The show didn't hold my interest, but it piqued my curiosity enough to check out the books, and I'm now a fan.  I must say, unlike the seeming majority, I quite like what they did with Bob's form on the show.  It was very different, but I think it fit the show's format to have a more anthropomorphic Bob.  The dead wizard in a skull thing was not as good as the books, but it humanized him, quite literally, for viewers of the show.
