No you could rent virtualised servers way before AWS. AWS simply had good marketing.

The virtualised server thing was not a AWS thing, the thing that was were their other services. For example instead of renting a virtual server and installing a database on it. You could rent the database; that was sort of a new thing that AWS made in to thing.

It was never cheaper what you paid for was a promise of fire and forget. You would no longer need to worry about any responsibility to update the server or the database cause the AWS crew took care of that.
