The NES made console gaming what it is today with an iconic controller and decent game franchises, many of which are still here today getting sequels. (there were good games before but not so much quality control) Also Nintendo saved the console industry from itself.
I would put the PS1 and Game Boy in joint second. PS1 because it made gaming very popular and a cool thing to do, not to mention the classic games are on it. Although I think Nintendo set the way forward in the industry with the NES. While, Game Boy also because it proved that proper handheld gaming was possible given the technology at the time.
