Although its literary origins are sometimes associated with the cyberpunk genre, steampunk works are often set in an alternative history of the 19th century British Victorian era or the American “Wild West”, in a future during which steam power has maintained mainstream usage, or in a fantasy world that similarly employs steam power. However, steampunk and neo-Victorian are different in that the neo-Victorian movement does not extrapolate on technology while technology is a key aspect of steampunk.
Steampunk most recognizably features anachronistic technologies or retrofuturistic inventions as people in the 19th century might have envisioned them, and is likewise rooted in the era’s perspective on fashion, culture, architectural style, and art. Such technologies may include fictional machines like those found in the works of H. G. Wells and Jules Verne, or of the modern authors Philip Pullman, Scott Westerfeld, Stephen Hunt, and China Miéville.[original research?] Other examples of steampunk contain alternative-history-style presentations of such technology as steam cannons, lighter-than-air airships, analogue computers, or such digital mechanical computers.
Steampunk also refers to any of the artistic styles, clothing fashions, or subcultures that have developed from the aesthetics of steampunk fiction, Victorian-era fiction, art nouveau design, and films from the mid-20th century.
