Steampunk City

Steampunk as popular fiction
William Gibson and Bruce Sterling's 1990 novel The Difference Engine is often credited with bringing widespread awareness of steampunk to a wider readership. This novel applies the principles of Gibson and Sterling's cyberpunk writings to an alternate Victorian era where Charles Babbage's proposed steam-powered mechanical computer, which he called a difference engine (a later, more general-purpose version was known as an analytical engine), was actually built, and led to the dawn of the information age more than a century "ahead of schedule".
The first use of the word in a title was in Paul Di Filippo's 1995 Steampunk Trilogy, consisting of three short novels: "Victoria", "Hottentots", and "Walt and Emily", which respectively imagine the replacement of Queen Victoria by a human/newt clone, an invasion of Massachusetts by Lovecraftian monsters, and a love affair between Walt Whitman and Emily Dickinson.
Alan Moore's and Kevin O'Neill's 1999 The League of Extraordinary Gentlemen graphic novel series (and the subsequent 2003 film adaption) greatly popularized the steampunk genre and helped propel it into mainstream fiction. Also The Adventures of Brisco County, Jr, a 1990s TV science fiction-western set in the 1890s, on Fox Network, used elements of steampunk when Professor Wickwire made his appearances with his somewhat futuristic inventions, many of which were described as "the coming thing".
