The origins of Bluetooth

Harald “Bluetooth” Gormsson (born c. 910—died c. 987) was a king of Denmark and Norway, best known in his time for introducing Christianity to the country. In recent times, his legacy continues in the oddest of forms. wireless Bluetooth technology is named after him, and the symbol is composed of the two runes spelling out his initials RB. The logo is a bind rune merging the Runic letters Hagall and Bjarkan. Something to ponder the next time you connect your headphones to your phone. Beep-boop.
