Yup, Douglas Adams' Hitchhikers Guide To The Galaxy was first broadcast on the BBC on 8th March 1978. It's officially the answer to life, the universe and everything years old.
Still my favourite radio series and book, even with the dreadful movie, the TV series killing off The Goodies, and most sadly, the death of Douglas.
It's influences is all over the place, the translation service Bablel Fish, Elon Musk, you could probably even make a claim for Wikipedia being influenced by it.

Douglas is an icon as well, one of only two people outside of the Pythons to be given a writing credit on the series (the other is Neil Innes), writer and script editor for Doctor Who, his work with endangered species too in Last Chance to See.
He even made a cameo as Agrajag in the 2004 Tertiary Radio Series of Hitchhikers Guide to the Galaxy even though he died in 2001...
So anyway, be a hoopy frood and know where your towel is, sit down and have a drink that is almost, but not entirely unlike tea, and binge on the BBC Radio 4 Extra specials that are going on tonight, starting at 8pm with the very first episode.
