An abstract RIFF chunk.
RIFF was introduced in 1991 by Microsoft and IBM, and was presented
by Microsoft as the default format for Windows 3.1 multimedia files. It is
based on Electronic Arts' Interchange File Format, introduced in 1985 on
the Commodore Amiga, the only difference being that multi-byte integers are
in little-endian format, native to the 80x86 processor series used in
IBM PCs, rather than the big-endian format native to the 68k processor
series used in Amiga and Apple Macintosh computers, where IFF files were
heavily used.
In 2010 Google introduced the WebP picture format, which uses RIFF as a
container.
