Commodore VIC-20 demos are demos written for the Commodore VIC-20 home computer.
On many classic 8-bit platforms, such as the Commodore 64 and the ZX Spectrum, the organized activity of democoding was started by crack intros, a side product of software cracking. This was not the case with VIC-20, whose userbase shifted to other platforms before the software pirates developed a crack intro culture of any kind. The VIC-20 demoscene was born at a much later time as an offshoot of existing scenes, particularly that of the Commodore 64.
