What is the origin of the WASD key scheme?

My gaming memories go way back to the Atari 2600 with its single-button gamepad, and with computer gaming I started with the PC XT.

Back in the day, movement would be controlled by the arrows and actions with the spacebar (and secondary actions with Ctrl, Alt, Shift, etc). That was the standard for a long time; I remember playing games on my Pentium with these key bindings.

Nowadays, WASD is almost universal, and even flash games on popular gaming sites accept these keys as movement input.

What was responsible for this change? Can it be traced back to a popular game, important event, or trend that introduced and shifted the tendency from the former to the latter? Or was it just a natural process? If so, why did everyone choose the same keys?

Answer

Wikipedia’s article on arrow keys covers some of the history of WASD:

The scheme wasn’t popularized until competitive play in Quake and subsequently QuakeWorld made clear its advantages over the older arrow key configurations.

Competitive Quake play only popularised the layout though, as it wasn’t the first time they were used:

In the same year that Castle Wolfenstein was released, 1981, the game Wizardry used the AWD keys for movement in a 3D dungeon. Both the programmers of Castle Wolfenstein and Wizardry were users of the earlier PLATO system where the game Moria used the AWD keys.

So they were popularised by Quake and the FPSs that followed and made it default, but they’d been around as a control scheme for a while already.
