At the same time demos from others, such as Antony Crowther (Ratt), had started circulating on Compunet in the United Kingdom.On the ZX Spectrum, Castor Cracking Group released their first demo called Castor Intro in 1986.
With many of the past's challenges removed, the focus in making demos has moved from squeezing as much out of the computer as possible to making stylish, beautiful, well-designed real time artwork – a directional shift that many "old school demosceners" seem to disapprove of.
This can be explained by the break introduced by the PC world, where the platform varies and most of the programming work that used to be hand-programmed is now done by the graphics card.
It is a competition-oriented subculture, with groups and individual artists competing against each other in technical and artistic excellence.
Those who achieve excellence are dubbed "elite", while those who do not follow the demoscene's implicit rules are called "lamers"; such rules emphasize creativity over "ripping" (or else licensing) the works of others, having good contacts within the scene, and showing effort rather than asking for help.
The first crack screens appeared on the Apple II computers in the late 1970s and 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.This gives demo-groups a lot more artistic freedom, but can frustrate some of the old-schoolers for lack of a programming challenge. Demo parties have competitions with varying limitations in program size or platform (different series are called compos).On a modern computer the executable size may be limited to 64 k B or 4 k B.The perception that the demo scene was going to extremes and charting new territory added to its draw.Recent computer hardware advancements include faster processors, more memory, faster video graphics processors, and hardware 3D acceleration.Prior to the popularity of IBM PC compatibles, most home computers of a given line had relatively little variance in their basic hardware, which made their capabilities practically identical.
