History of the Nintendo Entertainment System
In the late 80s, Nintendo's dominance was threatened by newer, technologically superior consoles. 1987, NEC and Hudson Soft released the PC Engine, and a year later, Sega released the 16 bit Mega Drive. Both were introduced in North America in 1989, where they were respectively marketed as the "TurboGrafx-16" and the "Genesis." Facing new competition from the PC Engine in Japan, and the Genesis in North America, Nintendo's market share began to erode. Nintendo responded in the form of the Super Famicom ("Super Nintendo Entertainment System" in North America and Europe), the Famicom's 16-bit successor, in 1990. Although Nintendo announced their intention to continue to support the Famicom alongside their newer console, the success of the newer offering began to draw even more gamers and developers from the original NES, whose decline accelerated. However, Nintendo did continue support of the NES for about three years after the September 1991 release of the Super NES, with the NES's final first-party games being "" and "Wario's Woods".

A 1983 industry crash, caused by the market being overrun with low-quality products, prompted a higher degree of regulation by future console manufacturers: when the Nintendo Entertainment System (NES) was launched in the United States in 1985, Nintendo of America instituted requirements and restrictions on third-party developers, including the requirement for all games to be licensed by the company. The console itself also included a lockout chip to enforce this requirement and prevent the console from loading unlicensed games. Such leverage on developers has since become a standard practice among console makers, although Nintendo of America also had stringent content policies, frequently censoring blood, sexual content, and references to religion, tobacco and alcohol from games released on its consoles in the United States.
