Because it is simply the most extreme show they can watch. It's target is extremely girly and for little kids. Phineas and Ferb, for instance, would be a great substitute for My Little Pony, however, it's gender-neutral and aimed for kids of all ages. It won't have the same *effect* as MLP would have. All going back to the bandwagon, of course. Why not something like Winx Club or W.I.T.C.H.? (ignore that fact that I'm aware of these shows) Had to Google that, ha. Well of course there's an community reason for the spark of MLP, but this massive bandwagon/popularity? As my post. That said, if the spark started with Winx...then this thread would be called something else. Actually, I've watched Winx, and I can honestly say that MLP is a better (or at least less bad) show. Winx, I feel, has a much more targeted audience, whereas MLP is not as ... piercing ... to a guy watching the show (much like in the sense of Powerpuff Girls. Maybe I'm an odd fellow). It's definitely better than a lot of the other cartoons currently running on my channels, which have poor / lacklustre characters, dialogue, graphics or a mix of those.
