The console market has steadily developed from simple one-off games (Pong) to fully featured general purpose games systems.
Older game consoles and their software now live on in emulators as they are no longer supported by their manufacturers. However, console makers try to prevent their games from being played on emulators using copyright-like exclusive rights in mask works and a protection of encrypted media created by the United States' Digital Millennium Copyright Act and foreign counterparts.
Note that the "bitness" of past generations (8-bit, 16-bit, 32-bit, 64-bit and 128-bit) were in large part created by the console makers' marketing departments and may have little to do with the actual architecture of the systems.
