Story behind the name Bluetooth, Why so called?

As we all know Bluetooth was invented by telecom vendor Ericsson in 1994 which is used for sharing the files over a short distance using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz from mobile devices.

Now a days we don’t use Bluetooth much as there are many files sharing alternatives are been invented and they are more faster and compatible. But there would be very few of us knowing the fact of the name Bluetooth, why it is called Bluetooth?


Well, If you don’t know the fact behind the name Bluetooth, then this article can help you to understand.

Of course there is nothing related to the teeth or being a blue color. The name is inspired by the the King of Denmark Harald Blatand in 958 to 970. The tenth century king Harald Bluetooth (Bluetooth in English, who got his name because of his fondness for blueberries, which stained his teeth.) had a very strange technique to communicate with the tribes to bring them together without any violence. Harald Bluetooth who united dissonant Danish tribes into a single kingdom and, according to legend, introduced Christianity as well.

The idea of this name purposed by Jim Kardach in 1997 who developed this system. At the same time Jim Kardach was reading the novel of The Long Ships about Vikings and King Harald Bluetooth. The Bluetooth was invented to allow connectivity and collaboration between different devices. Hence this system was named as Bluetooth.


The logic behind the logo of bluetooth is also related to Herald Bluetooth’s initials to give the tribute to the contribution of the legend. The two lines sticking out of the back of the B actually represent a Runic H — that H for Harald (The Runic H is like an asterisk in English). And the B stands for Blatand!
