HIGHLIGHTS

  • The technology is named after King Harald “Bluetooth” Gormsson, who was well known for uniting Denmark and Norway in 958.

Bluetooth is a wireless Technology for short-range wireless interconnection of cell phones, computers and other electronic devices. This is what most mobile phone users in the world know.

It’s a technology that has enabled millions of people to quickly transfer digital data between devices over short distances and connect to other devices in mere seconds.

Bluetooth was invented over two decades ago and its logo has become a universal sign of connectivity due to its widespread use.

Although it is very easy to identify the iconic logo which looks like the letter “B”, many of us are unaware that there is a hidden meaning behind the design and the name.

Well, the meaning of the logo was recently explained on Bluetooth.com.

“We all recognize the ‘Bluetooth’ brand, but take its importance and impact on our lives for granted. From smartphones to headphones and beyond, we rely on Bluetooth technologynology to free us from the tether of wired technology,” the website said.

The name is not an acronym. It actually dates back over a millennium to King Harald “Bluetooth” Gormsson.

He had nothing to do with technology but was well known for uniting Denmark and Norway in 958, and his dead tooth, which turned dark blue, earned him the nickname “Bluetooth”.

The design of the Bluetooth wireless specification was named after the king in 1997, based on an analogy that the technology would unite devices in the same way that Harald Bluetooth united the tribes of Denmark into one kingdom.

Harald “Bluetooth” Gormsson was the son of King Gorm the Elder and Thyra Dannebod. He ruled as King of Denmark from c. 958 – c. 986.

Harald also ruled Norway after the assassination of King Harald Greycloak.

The idea for the name and the technology was launched in 1996 by industry leaders Intel, Ericsson and Nokia. Their goal was to plan the standardization of short-range radio technology to support connectivity and collaboration across different products and industries, explains the Bluetooth website.

Interestingly, Bluetooth was not the official name for wireless technology at first. The plan was to replace it with RadioWire or PAN (Personal Area Networking). However, the name Bluetooth quickly caught on and had already garnered tens of thousands of hits on the Internet.

It eventually became the official name after a full trademark search on RadioWire could not be performed in time for launch.

“The Bluetooth logo is a linked rune merging the Younger Futhark (Hagall) (ᚼ) and (Bjarkan) (ᛒ) runes, the initials of Harald,” the website states.
