Why Is Bluetooth Called Bluetooth?

When two devices need to talk to each other, they need to have a handshake on various parameters before the conversation starts. The first agreement is on the medium – will they use wires, or talk over some wireless signal ?
Bluetooth is one such wireless signal (protocol) over which two (or more) devices communicate over.
Strange name though isn’t it – are the bluetooth waves invisible but blue and shaped like teeth? Wrong!
There is absolutely no relation between the name and the meaning.
The Bluetooth protocol was created by Ericsson (pre-Sony Ericsson) which is a major Swedish telecommunication company. They named it after the Danish viking king, Harald Blåtand. As legend goes, Blåtandhad the blessed ability to bring people negotiate with each other, and cometo talking terms.So skilled was he, that he was able to unite Denmark and Norway together! The literal translation of Blåtand means blue-tooth, hence the name Bluetooth for the protocol. It does precisely what Blåtand did – lets two wireless device to communicate with each other!
The Bluetooth symbol has HaraldBlåtand’sinitials inscribed into it (in Runic).
The two lines stickingout of the back of the B actually represent a Runic H – thats H for Harald .The B for Bluetooth also stands for Blåtand!
