Origin of the Team's

Everyone know's the massive battle between the Team Edward fans and the Team Jacob fans. Although, where did these teams come from. Stephenie Meyer specifically said that she didnt intend the fans would choose sides from Edward, Jacob or any other character from Team Emmett, Team Carlisle, Team Paul etc. I just had a brainwave..i know where the teams came from..well sorta. Remember when everyone was little and they used to watch Pokemon?? Well, Team Rocket anyone?? LOL I totally 4got about it untill a friend sent me a facebook group request about it. I thought it was hilarious!! :)
