The Commodore 64 Demos for the Commodore 64 were as far as is known the first real demos produced on any home computer.

The first demos on the C64 were not called demos but letter, message, supermessage etc. They were initially produced by the same people that cracked software protection, e.g. The 1001 Crew. The label "demo" appeared later.

Among the earliest demos are:

  • Borderletter from The 1001 Crew
  • Think Twice I-V by The Judges

These demos would later evolve into a subculture of it's own, resulting in massive parties where demo writers would compete. For the C64 the peak point in time for this culture was the year 1989 and the place was northern Europe. Here, hundreds of Dutch, French, Belgian, German, Danish, Swedish, Finnish and Norweigan groups would meet, for example at Venlo in Holland.

When the Commodore Amiga appeared, many former C64 demo programmers switched platform and continued to make demos, but for the Amiga. See Amiga Demos. The Atari Demos were also heavily influenced by the C64 demos.
