Where can you watch the 2000 Pokémon series?

I'm currently watching season 1 on Netflix but there are several there, so far not. Where can I still look, legally?

As far as I know only on netflix but there's only one season

Pokémon Company / Nintendo makes many Pokémon episodes available on the official Pokémon website via Pokémon TV. You have to see for yourself whether your desired episodes are included.
