Copy party
Gatherings where home-computer users showed up with a box of floppies and copied each other's games — the pirate ancestor of the demoparty.
Through the 1980s hundreds of teenagers travelled to weekend meets with their C64s and Amigas to swap and copy software — mostly games — on the spot. A copy party was as much a social hub as a distribution channel: this is where the warez scene's letter-writing "swappers" met face to face and handed over the latest cracked titles.
As interest shifted from piracy to home-grown demos and competitions, the meets changed character and name. The copy party became the demoparty, the big screen replaced the floppy swap, and the contest became the point — but the lineage still shows in how a demoparty is run today.
