In Japan, the Super Famicom easily took control of the gaming market. In the US, due to a late start and an aggressive marketing campaign by Sega (Headed by the Sega Company's new mascot, Sonic The Hedgehog, their answer to Nintendo's Super Mario), Nintendo saw its market share take a precipitous plunge from 90-95% with the NES to a low of approximately 35% against the Sega Genesis. Over the course of several years, the SNES in North America eventually overtook the Genesis, thanks to franchise titles such as "Super Mario World", "", "Street Fighter II", and the "Final Fantasy" series. Total worldwide sales of the SNES reached 49.10 million units, eclipsing the estimated 40 million unit sales of the Genesis.
