Why Bluetooth?

Why Bluetooth?
Now that we’ve had our history lesson, the question still remains: Why is this new wireless
technology named after a 10th-century Danish king? It’s all about King Harald’s ability to
unite. Like King Harald, the Bluetooth technology unites people and enables them to talk to
each other. Thus King Harald Bluetooth, the uniter, gives name to Bluetooth, the uniting
technology.
(Paying respect to King Harald, the official Bluetooth logo, shown in Figure 2.3, is composed
of the runic characters H and B—for Harald Bluetooth.) Oh, and about King Harald’s second name. “Bluetooth” (or Blåtand, in Danish) doesn’t have
anything to do with the color of his teeth. Instead, it refers to his unusually dark complexion
and his very dark hair. The word “Blåtand” is apparently derived from two old Danish words,
“blå,” meaning dark skinned, and “tan,” meaning great man. In the land of fair-skinned
Nordic blondes, Harold’s distinct coloration apparently stood out like a… well, like a blue
tooth.
