The scene started with the home computer revolution of the early 1980s, and the subsequent advent of software cracking. Crackers altered the code of computer games to remove copy protection, claiming credit by adding introduction screens of their own ("cracktros"). They soon started competing for the best visual presentation of these additions. Through the making of intros and stand-alone demos, a new community eventually evolved, independent of the gaming and software sharing scenes.

Demos are informally classified into several categories, mainly of size-restricted intros. The most typical competition categories for intros are the 64k intro and the 4K intro, where the size of the executable file is restricted to 65536 and 4096 bytes, respectively. In other competitions the choice of platform is restricted; only 8-bit computers like the Atari 800 or Commodore 64, or the 16-bit Amiga or Atari ST. Such restrictions provide a challenge for coders, musicians, and graphics artists, to make a device do more than was intended in its original design.

History

The earliest computer programs that have some resemblance to demos and demo effects can be found among the so-called display hacks. Display hacks predate the demoscene by several decades, with the earliest examples dating back to the early 1950s.

Demos in the demoscene sense began as software crackers' "signatures", that is, crack screens and crack intros attached to software whose copy protection was removed. The first crack screens appeared on the Apple II in the early 1980s, and they were often nothing but plain text screens crediting the cracker or their group. Gradually, these static screens evolved into increasingly impressive-looking introductions containing animated effects and music. Eventually, many cracker groups started to release intro-like programs separately, without being attached to unlicensed software. These programs were initially known by various names, such as letters or messages, but they later came to be known as demos.

In 1980, Atari, Inc. began using a looping demo with visual effects and music to show the features of the Atari 400/800 computers in stores. At the 1985 Consumer Electronics Show, Atari showed a demoscene-style demo for its latest 8-bit computers that alternated between a 3D walking robot and a flying spaceship, each with its own music, and animating larger objects than typically seen on those systems; the two sections were separated by the Atari logo. The program was released to the public. Also in 1985, a large, spinning, checkered ball—casting a translucent shadow—was the signature demo of what the hardware was capable of when Commodore's Amiga was announced.

Simple demo-like music collections were put together on the C64 in 1985 by Charles Deenen, inspired by crack intros, using music taken from games and adding some homemade color graphics. In the following year, the movement now known as the demoscene was born. The Dutch groups 1001 Crew and The Judges, both Commodore 64-based, are often mentioned among the earliest demo groups. While competing with each other in 1986, they both produced pure demos with original graphics and music involving more than just casual work, and used extensive hardware trickery. At the same time demos from others, such as Antony Crowther, had started circulating on Compunet in the United Kingdom.
