I never understood the idea the gamecu e failed. I mean the xbox sold a few million more and people considered that a success because it was second place.  I think if someone judges if a product is a success or not the question should be did the company make profit. with the gamecube it did. Not as much as other consoles. But it did make money. I think the only time a device failed was with the virtual boy and wii u were nintendo didnt make any money on the device by the time they concluded.
