One interesting domain-specific class of compression algorithms not mentioned here is for lossless audio compression, which tends to use a different (though also pretty simple) technique, somewhat related to PPM. A common approach is to predict the waveform using linear predictive coding (LPC), and then entropy-code the residuals. FLAC does that, for example.
