I remember reading a Pokémon Annual that my sister had when I was about 3. It had a comic version of the first movie, and it really got me interested in Pokémon. The first episode I remember watching was Cerulean Blues, at my friends house, though I'm sure I watched some of the Johto series episodes before that, I just can't remember them. I've watched all of the Sinnoh, Kanto and Orange Island Episodes since then, and I'm keeping up to date with the Unova ones, and regularly watching the Johto ones (Currently on turning over a new Bayleef!).
