Using the domain name steampowered.com will finally make sense 20 years later.
It still reminds me of how it took me about a decade to finally realise the connection between steam (as a gaseous substance), Steam (the platform), valve (as in that rotating thing to release pressure) Valve (the corporation), steampowered (the domain name) and steam-powered (as in a steam engine).
The logo of steam is the crankshaft of a steam engine
The old steam consoles were called “steam machines” with the “piston” being one of them
The distribution system is called “steam pipe”
I’m sure I’ve forgotten some of their puns
Edit: Ah. There’s also “Steam Cloud” of course
