Indigo League now available on Amazon
Update: The digital release of Pokémon: Indigo League is no longer available for purchase on Amazon. "Pokémon: The Journey Begins" is unaffected.
The entire 52-episode first season of the Pokémon anime, called Pokémon: Indigo League, is now available on Amazon digitally. The season is available in four volumes of 13 episodes each. Amazon claims that these episodes are in high definition (HD).
Each of the four volumes cost US$21.99, for a total of US$87.96 for the entire season (due to the way Amazon is configured, the volumes are incorrectly described as seasons). Episodes can be purchased individually for US$2.99 each.
Note that this release uses standard seasons (as seen on Pokémon.com and in Australian home video releases), rather than Viz Media seasons (which corresponds to opening themes and are used in North American home video releases), so it does not contain the entire Indigo League arc.
