The official Pokémon Youtube Channel is now available at: http://www.youtube.com/pokemon/. The official Pokémon website announced the channel and launched the debut music video "Can't Stop (Catchin' 'Em All)" by The Presidents of the United States of America. The Pokémon Youtube Channel also has movie trailers, game trailers and various other videos. Video embedding on website has been disabled on the account though, making the channels videos quite pointless, especially considering most of them are advertisements that are to be viewed as much as possible. Below is the description from the channel.
