The bit ratings of consoles in the 5th generation began to blur & were less of a selling feature than the previous "bit wars" of the 8 and 16 bit era. The number of "bits" in console names referred to the CPU word size. It had been used by hardware marketers as a "show of power" for many years. The fifth generation saw the increase of emulation. The development of the Internet made it possible to save and download tape and ROM images of older games. This led the seventh generation consoles to make many older games available for purchase or download.
