PostScript

PostScript is the most misunderstood widely known programming language in the world. Surely widely known in the sense that, because of its enormous use, many have heard of it. And indeed misunderstood as most of them have no idea that it is a programming language at all, perceiving it as a file format for laser printers to read.
