The fourth generation of video game consoles was started by the launch of NEC's PC Engine in 1987 in Japan. While the PC Engine used an 8-bit CPU, it included 16-bit graphic rendering components, and NEC marketed this heavily as a 16-bit game console to distinguish it from the Famicom and Mark III; when NEC brought the PC Engine worldwide, it was rebranded as the "TurboGrafx-16" to emphasize this. Though the practice was considered deceptive by NEC's competitors[citation needed], the use of the bit designation caught on, and led manufacturers to focus their advertising heavily on the number of bits in a console system for the next two console generations.[1]
