In March 1978, over thirty years ago, a science fiction comedy series
called The Hitch Hiker's Guide to the Galaxy was broadcast on
BBC Radio 4 in the United Kingdom. It contained a character called Marvin, the
Paranoid Android. Marvin was fitted with the new GPP Feature
(Genuine People Personalities). Unfortunately, Marvin was a personality
prototype - Marvin was a manically depressed robot.
