Scanned documents done cleverly: DjVu, built at AT&T Labs in the late 1990s, separates a page into a sharp bitonal text layer and a low-resolution background, compressing each with the codec it deserves — book scans came out dramatically smaller than the JPEG-in-PDF alternative of the day. PDF's gravity won anyway, but enormous library and archive collections remain in DjVu, so readers keep the format alive. It is an IFF-style chunked container, and standard files open with the four bytes AT&T, one of the few formats whose magic number is its corporate parent's logo.

.djvu is one document; .djv is the same thing abbreviated — multi-page bundles use the DJVM form inside.
