Toyota as Japan's most successful corporation. By early 1992, more than units had been sold worldwide, with in the United States by early 1993. Its popularity greatly affected the computer-game industry, with executives stating that "Nintendo's success has destroyed the software entertainment market" and "there's been a much greater falling off of disk sales than anyone anticipated". The growth in sales of the Commodore 64 ended; Nintendo sold almost as many consoles in 1988 as the total number of Commodore 64s had been sold in five years. Trip Hawkins called Nintendo "the last hurrah of the 8-bit world", with Nintendo having completely destroyed the Commodore 64 game market as of Christmas 1988. Market decline (1990–1995) In the late 80s, Nintendo's dominance was addressed by newer, technologically superior consoles. In 1987, NEC and Hudson Soft released the PC Engine, and in 1988, 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 its intention to continue to support the Famicom alongside its newer console, the success of the newer offering began to draw even more gamers and developers from the NES, whose decline accelerated. 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 Zoda's Revenge: StarTropics II and Wario's Woods. In Christmas 1991, both the NES and SNES were outsold by the Sega Genesis in North America. This led to Nintendo's share of the North American market declining between 1991 and 1992. In contrast, NES sales were booming in Europe during that same period. A revised Famicom (HVC-101 model) was released in Japan in 1993. It takes some design cues from the Super NES. The HVC-101 model replaces the original HVC-001 model's RF modulator with RCA composite audio/video output, eliminates the hardwired controllers, and features a more compact case design. Retailing for ¥4,800 to ¥7,200 (equivalent to approximately $4260), the HVC-101 model remained in production for almost a decade before being finally discontinued in 2003. The case design of the
