File:Doom clone vs first person shooter.png: This is a fantastic graph showing how the video gaming community transitioned from Doom to the more general concept of the first person shooter (FPS).

It shows Usenet postings from 1993 to 2002, graphed by usage of the phrase “doom clone” and “firs person shooter.” In the beginning, everything was a “doom clone.” Then came others, and the more generic term started to prevail.
