My favorite story about Viterbi encoding is that apparently they launched the Voyager probe with a Viterbi encoder even though at the time there wasn't a computer on Earth capable of decoding it in real time (encoding is less computationally intensive than decoding). Years later they remotely switched over to Viterbi to enable higher bitrates.
