Fiat was the first ever to come up with such a system in 4 stroke engines, and Alfa Romeo was the first to use it in production cars. Nissan then came with something similar and I believe Honda came afterwards. But I've always clearly remembered Fiat and Alfa Romeo being the first.
I believe what the original poster meant was that little controller some Honda users have to activate the old V-TEC system at a different RPM. I think I once saw something like that for Toyota's system, but that was just once on some ad in a website years ago.
