Bluetooth logo

The word "Bluetooth" is an anglicized version of the Scandinavian Blåtand/Blåtann, (Old Norse blátonn) the epithet of the tenth-century king Harald Bluetooth who united dissonant Danish tribes into a single kingdom, according to legend, introducing Christianity as well. The idea of this name was proposed in 1997 by Jim Kardach who developed a system that would allow mobile phones to communicate with computers. At the time of this proposal he was reading Frans Gunnar Bengtsson's historical novel The Long Ships about Vikings and king Harald Bluetooth.[7][8] The implication is that Bluetooth does the same with communications protocols, uniting them into one universal standard.[9][10][11]

The Bluetooth logo is a bind rune merging the Younger Futhark runes (Hagall) (?) and (Bjarkan) (?), Harald's initials.
