The story of Harald with blue teeth!

The little story of the Bluetooth logo

Everyone knows the "Bluetooth" logo, but do you know the origin of this name and its logo?
It is a unique story, much deeper than it seems. Personally, I've always taken that name for a kind of funny and offbeat joke.

In an article published in the Reddit thread, a user shares the roots of the emblem of this technology. The Bluetooth logo would be the combination of the letters "H" and "B", the initials of King Harald Bluetooth (in Danish "Harald Blåtand") written in the runic script used by the Vikings.

Below: The runic alphabet or futhark - a term formed from the name of its first six letters - is an alphabet that was used for the writing of Germanic languages by peoples speaking these languages, such as the Scandinavians, Friesians, Anglo-Saxons, etc. There are also Hungarian and Turkish runes, two independent systems (Source: Wikipedia).

Then why did Intel engineers dig up a Danish king to name their technology? 

In 1996, Jim Kardach, an Intel engineer, worked on the development of a system that would unify phones with computers using wireless communication technology. At this point the proposed names look like Biz-RF, MC-Link or Low Power RF! In other words, names as unoriginal as "Microsoft" compared to "Apple". All these names will be rejected by the legal department because of their too generic names. This is where a Danish collaborator from Kardach talks to him about "Harald with blue teeth", the king who unified Denmark and Norway between 958 and 987.

The name was there, with the promise of unification of electronic devices at the same time.
A great example of successful naming!

From then on, the logo appeared very quickly by combining Harald Blåtand's initials: (Hagall) (ᚼ) and (Bjarkan) (ᛒ).
