Kongernes Jelling

The connection between your phone and an old Viking king


Do you know why it is called Bluetooth? Now a Danish Museum will tell the story through several events and an entirely new exhibition at Kongernes Jelling, Denmark – Home of the Viking Kings - on October the 10th and 11th.

This year it is 25 years ago that Bluetooth was named after a Danish Viking King. One of the founding members is Örjan Johansson from Sweden. He was Director & General Manager for Bluetooth Technology & Products and in October he will be in Jelling to celebrate.

25 years ago, when the Ericsson invention met competition from other wireless technologies, we could hardly believe the development to one of the worlds most used technologies.

Less known is the design of the patent peace treaty agreements currently between more than 40.000 companies around the world, which makes it easier to evolve Bluetooth with ever new functionalities and will make Bluetooth evolve as an eternal name and technology," says the former Ericsson.

It may sound bold but in fact the title makes a lot of sense. When the American engineer Jim Kardach from Intel came up with the name for the new technology back in the 90s, the inspiration came from king Harald Bluetooth who ruled Denmark a thousand years ago. Harald Bluetooth united all of Denmark and Norway and told us about it by erecting the largest runestone in the world – in Jelling.

Engineer and technical leader from Intel Jim Kardach was looking through a book about the Vikings and beneath a picture of the famous rune stones of Jelling, the name Bluetooth caught his eye.

The idea behind the new technology was that it should connect and unify. Just like Harald Bluetooth did when he unified Denmark and Norway. Hence the new wireless tech. ended up with the same name. Originally during development we would get news articles stating: "The Bluetooth group, named after a 10th century Danish King, is developing a short range radio cable replacement technology.

Every article would provide the relationship to the Danish King, and then identify it as a cable replacement technology. People immediately recognize the word ("blue" and "tooth"), but have no idea what it means. That short paragraph provides a context (named after a Danish King) and what it is (a radio that replaces a cable). The effect is similar to ear-worms; songs that when you hear them, you can't get them out of your head”, says Jim Kardach, who also joins the events in Denmark on October the 10th and 11th.

The celebration kicks off October 10th and 11th in Bluetooth’s own backyard of Jelling, Denmark. The two days are called: Bluetooth Is Coming Home.

There will be workshops, a new exhibition will open and 7 of the founding members will take part in workshops, talks and celebrations.
