Perforce is probably more widespread than people realise, and not just games industry although they've focused more on the benefits they bring to that field in recent years. Perforce were offering a good quality version control system for years before the initial release of git, as a result it can still be found in many older companies who have projects that are older than git itself and haven't migrated. Git has obviously won the VCS battle now in most fields, but version control used to be a much more diverse and interesting space; I'd used Perforce, SVN and Mercurial professionally before git just won out most places.
