There are some very good ones in this thread but I'll have to go with the entire Dreamcast scene.
The discovery of the MIL-CD entrypoint which kickstarted it all, the release of the first Utopia Bootdisk and Action Replay/GameShark CDX, both of which later on became obsolete when used to boot backups & homebrew by selfbooting disks, the rise of brilliant homebrew apps like DreamShell and awesome hardware hacks like the SD adapter...
Taken by itself, it might seem like any other hacking scene where the line between homebrew and piracy is very blurred. However, what's so mind-blowing to me is that the exact same thing which many say killed the Dreamcast has allowed it to survive much past its discontinuation date. Think about it: a console that got released worldwide around 20 years ago is still getting homebrew and commercial indie releases to this very day and we're talking about something that was considered a big commercial failure.
