If only lasted 4 years. Why did it fail? I can't think of any other channel that had as short of a run in the united states. Whether its defunct channels like Discovery Kids or Toon Disney or still active channels like Nicktoons, Disney XD, Nick, Cartoon Network, and Disney Channel. Why did The Hub last for so short of a time, it didn't even make it to 5 years?
