Marvin, the Paranoid AndroidIn 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.
