Votedisk
The floppy holding every competition entry, handed out at a demoparty so attendees could vote the winners.
At 1990s demoparties all the compo entries were gathered onto a votedisk (or "voting disk") that was copied round to the crowd. You looked through the demos, graphics and music at your own pace, filled in your votes and handed the disk back — the votes decided the rankings, and so whose group got to brag hardest.
The system was eventually replaced by parties' own networked voting and later by services like Pouët and Scene.org. The votedisk was both a practical solution and a distribution channel in its own right: the entries reached everyone on site before they had even been officially released.
