Long story short: during the lead up to the English release of Pokémon the Movie 2000, Nintendo gave Warner Bros. permission to release tie-in products to promote it. Warner Bros. opted to commission Cyberworld International Corporation to create a short browser game to that end. According to Eddie Ruminski, an employee who kept the files and allowed them to be shared online, the game was downloaded more than 1,000,000 times within a month - which led to Nintendo forcibly shutting it down, as they felt the game was "[exceeding their] contract's allowable scope."
