WMV belongs to the same broad media era as ASF and Windows Media Player–oriented distribution, when platform ecosystems shaped online media choices much more directly.
PGM Raw at a glance
PGM Raw
The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.
