Yes, id invented it, but I think they published one slightly earlier game which also had texture streaming. The technique (virtual textures) would not become ubiquitous in most engines until the PS4 era though.

Enemy Territory: Quake Wars used an earlier version of it but only for the terrain. I think Rage was the first to use it for everything.

		Unfortunately nowadays id Software doesn't seem to be at the cutting edge of engine technology anymore. Most interesting new developments now come from Unreal Engine as far as I can tell. Like virtual geometry (Nanite) or efficient ray traced direct illumination (MegaLights).
