You get a demogroup. Demogroups made up a subgenre in computing. (They still do)
When I started to get into computing as a hobby, outside my childhood home. I was exposed to demo's around the year 1992. Computers was my hobby from around 1986 or 1988 though, when my parents bought a Unisys 80286 machine. (A little side-note)
In 1992 I saw my first demo called "State of the art" by a group called Spaceballs. This demo was awesomme, it ran on an Amiga500 and it just hit me like a train. I was completely mesmerized.
Today, this demo just seems kind of primitive, yet it was THE shit to have on a 880 kilobyte Amiga formatted 3.5inch floppy disc. And looking at the specs. for the Amiga500 today, it is actually pretty good. The Amiga500 had a 7.14mhz (yes. megaherz, not giga). It had 512kilobyte of memory and everything was loaded from a floppy as standard. Though harddrives were sold, at the same price as the machine it self.
Where do demo's originated from? The answer is actually simple. Demo's originated from the Commodore64 and other 8-Bit machines. Back then, there were copyprotection on most games and programs. As well as today.
And people began "cracking" those games, in order to pirate them. And in many cases sell for a profit. And to stiffen off the competition, they started to advertise in a form of simple cracking-intro or in other words. A graphical presentation. They called it for a Cracktro, the word's "Cracking" and "Intro".
Time went by, and eventually the concept of Cracktro's evolved into a standalone presentation. Dubbed "Demo's", and new young artists/programmers saw a potential for a new kind of hobby. They started to compete big time.
The legazy from the old cracktro days, can still be found in moderne key generators.
Using some elements of C64 graphics and music style.
New technology eventually pushed the Amiga out, as the number one platform on wich to create demo's. I guess it started around 1993/95, as some remarkable demo's for the pc were released. Before that, only a couple of demo's on the pc platform is noteworthy to mention here. (I will do it anyway)
The first one is "Crystal Dreams" from a group called Triton. A nice little one, that has some 3D-Graphics. The second one is "Second Reality" from a group called Future Crew.
Today, the demoscene is not what it was. Well... It is still awesomme products they produce. New groups have come and old ones have left. Only a small handfull of groups, like Razor1911 is still active. And yes. They still do some good shit.
