Nintendo actually had a larger monopoly in the 1990's, and had much more competition at least terms of number of competing systems(Sega Game Gear, Atari Lynx, Sega Nomad, Neo Geo Pocket, etc.). PSP has been the only system ever to seriously challenge Nintendo's handheld crown. The only difference is now the number of competitors is small and the the sales are higher for them.
