A lot of GNU/Linux software will either default to or demand
PNM images for input/output.

One program that comes to mind is the SANE scanning package
where scanimage will output PNM format only.

The reason is PIPES.

All the programs within NetPBM can be piped together to provide
a processing chain.  It is thus convenient to have software
output in PNM format so that it can be immediately piped
into a processing chain.

This is the traditional Unix way.
