Well, I used three version control software: cvs, svn, mercurial. While I agree that the latest is better, I feel it is a bit of an exageration to say that previous to git/mercurial, versioning was difficult or impossible. Many people say git and github are the best invention in the latest years, but I don't see that it had really changed the industry compared to good ol' cvs.
