The Hitchhiker's Guide to the Galaxy (sometimes referred to as HG2G, HHGTTG or H2G2) is a comedy science fiction series created by Douglas Adams. Originally a radio comedy broadcast on BBC Radio 4 in 1978, it was later adapted to other formats, including stage shows, novels, comic book adaptations, a 1981 TV series, a 1984 computer game, and 2005 feature film. The Hitchhiker's Guide to the Galaxy has become an international multi-media phenomenon. The novels are the most widely distributed, having been translated into more than 30 languages by 2005.
