I wonder if we're entering a 'big fandom' drought; a friend of mine recently pointed out that there are few SF genre shows left on U.S. television, and little on the horizon with "new and shiny" potential. It could almost be like what's happened in general over the last few decades with U.S. network television, where the top shows used to command tens of millions of viewers but now the audience has fragmented as a lot of niche programs attract followings on cable.
