Simply, these are the tales of a cybernetic future, lived more in cyberspace than meatspace, specifically as seen from the underside of society, the criminal, the usually impoverished, the subaltern. It also includes any society obsessively absorbed in media, and the protagonists may be revolutionaries

Before William Gibson’s Neuromancer in 1984 — perfect choice of years, huh? — dark and gloomy views of an unhappy technological future were simply known as “dystopic SF”; by those of us who cared. As a result, there was already a lot of stuff hanging around waiting to join this genre when it was noticed.

It’s heyday was the 1990s, but it still shows up: it just isn’t jumped all over as The Fashion any more.
