What is Steampunk

Steampunk / Dieselpunk are closely related topics often interchangeable. Steampunk is Victorian era + fantasy. Simple equation. Fantasy can come in the form of Odd machines, crazy fantastical one or just a juxtaposition of new age inventions in a time that they didn't exist.
Diesel punk is similar but the time period is slightly later, when they had fully converted from steam to diesel fuel. This simple formula can lead you to understand a genre of movies and film under their new categorization. If there was a movie back in the day that you enjoyed and it was just called Sci-Fi it may be called Steampunk now.
Where does the Punk come in? The punk comes in the case that it is out of the norm, there can be sometimes a lack of punk attachments to something that is totally steampunk. Confused yet? Well join the club. There are tons of people who enjoy things like this but don't know how to look for new stuff that suits them.
I enjoy The Adventures of Brisco County Jr, which by all accounts was and is a horrible show. I however bad it may be love it, for all it's tainted goodness. It is one of the best examples of steampunk.
What is Cyberpunk then? Cyberpunk is the forefather of Steampunk. That's were the roots of it's title came from. Bladerunner seems to be the begining of the title of that genre. Cyberpunk was big in the 90's. Steampunk seems to be conquering the current age.
