The Origin Of The Term "Bluetooth"

Harald "Bluetooth" Gormsson (Old Norse: Haraldr Blátǫnn Gormsson; Danish: Harald Blåtand Gormsen, died c. 985/86) was a king of Denmark and Norway.

The first documented appearance of Harald's nickname "Bluetooth" is in the Chronicon Roskildense (written c. 1140).

The Bluetooth wireless specification design was named after the king in 1997, based on an analogy that the technology would unite devices the way Harald Bluetooth united the tribes of Denmark into a single kingdom. The Bluetooth logo consists of a Younger Futhark bind rune for his initials, H (ᚼ) and B (ᛒ).
