Bluetooth name origins

King Harald Bluetooth, who united Denmark and Norway, was the inspiration for the name of this wireless communication standard. As the makers of Bluetooth were trying to allow PC and mobile devices to communicate without cables and in a sense unify them, king Harald was seen as an ideal symbol. This famous Viking ruled Denmark in the later part of the 10th century.

The Bluetooth logo is composed of two Nordic runes signifying king Harald’s initials — Harald Blåtand.
