But in the 80's, CompuServe defined an image format called GIF and used LZW compression in defining it. Well, of course once the uproar about these patents became known, people defined another image format using a different compression algorithm. They used the GZIP algorithm, and that format is called PNG format, which I suppose means &ldquo;PNG is Not GIF.&rdquo;
