There are a few things perhaps you could clear up.
a. What does the title of the site refer to?
b. Please define the "Demo Scene". Perhaps I have a misconception but don't want to embarrass myself.
This is going to be a long winded answer! But I'll try to answer as best I can, we'll do your second question first. (a potted history of demoscene).
B:- Demo Scene evolved from the early home computers when games makers would put some rudimentary copy protection on thier software to prevent people from pirating it and spreading to thier friends.
Some people started to de-protect these games so that they were freely copyable, protection became more advanced and crackers had to learn more code to be able to de-protect games.
Some of the crackers formed organised groups.
The first crack intros were simple, with just some text to say who cracked the game, as the crackers became more competant at code these messages evolved more and more into crack intros bearing the logo of the group, music and effects that were often better to look at than the game.
As these crack intros became more elaborate and spectacular some people started demo groups, often dedicated to demo programming and the demos became more and more advanced, multi part demos became common place and a real rivalry developed between demo scene groups with organised parties and competitions.
Crack intros are still produced, demos have moved on to become somnetimes beautiful masterpieces with many many disciplines, for example, 1kb intros, 256 byte intros, 64kb intros etc etc...
The scene lives on, as do the parties and demos. There are some very big parties such as Evoke, Function and Breakpoint, but there are dozens and dozens more.
Quite a lot of people on this forum are part of one or more scene groups.
A: - DBF+GVY demo code forum.
DBF is short for Dark Bit Factory.
GVY is short for Gravity.
Both are groups, Dark Bit Factory was started by me and a good friend called Franck Chevassu (Parabellum). Dark bit factory forum was originally for members of DBF only, but it became a popular place for programmers of demos to hang around.
It's by no means a scene community, there are other places for that like bitfellas, intro-inferno and pouet, but nevertheless so very well known sceners are contributing members here.
The group DBF died but in fact it would be fair to say that it evolved into this forum.
The group Gravity was started by Clyde Radcliffe and Rbraz, Rbraz is now a member of Ravebusters but the group Gravity lives on with other members, Clyde is still around, he has a new musician called Jojo, I am not sure if Ghost is still in as an artist
Gravity was added to the title of the forum because Clyde, Rbraz and Ghost helped me and Franck and the other DBF members get the board off the ground.
Hope that answers your questions
