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.
