It was invented by Robert K. Jung. ARJ stands for Archived by Robert Jung.
ARJ was one of two mainstream archivers for MS-DOS and Windows during early and mid-90s, with PKZIP being its competition.
In recent times, other alternatives to the ZIP archive, such as WinRAR have surpassed ARJ in market share; the lack of an official graphical version may have contributed to ARJ's decline.
