You’ll definitely recognize it, but it turns out that there’s a clever hidden meaning behind the Bluetooth logo that most of us know nothing about.

The wireless tech has become such a normal part of life that most of us barely think twice before tapping it on to connect to our headphones, speakers, or our car.

But the famous symbol and unusual name actually trace all the way back to a Viking king from over 1,000 years ago.

And once you know, you’ll never look at that little blue icon the same way again.

The hidden meaning behind the Bluetooth name is surprisingly brilliant

For such a modern piece of tech, Bluetooth has a seriously old backstory.

According to Bluetooth’s official site, the name comes from King Harald ‘Bluetooth’ Gormsson, who was known for uniting Denmark and Norway in 958.

He also reportedly had a dead tooth with a dark blue-grey color, which is how he earned the nickname Bluetooth.

That connection turned out to be the perfect fit for the technology.

Back in 1996, Intel, Ericsson, and Nokia were working together on a short-range wireless standard that could connect different devices and industries.

During one of those meetings, Intel’s Jim Kardach suggested “Bluetooth” as a temporary code name because King Harald had united Scandinavia, just like the new technology was meant to unite the PC and cellular worlds.

It was only supposed to be a placeholder, but sometimes the temporary idea ends up being the best one.

The logo is even smarter

The name is clever enough, but the logo takes it one step further.

That angular Bluetooth symbol is actually made from two runes, Hagall and Bjarkan, which represent Harald Bluetooth’s initials.

Put together, they form the now-iconic emblem that shows up on phones, laptops, cars, headphones, and pretty much every gadget imaginable.

So what looks like a simple futuristic symbol is actually a nod to medieval history.

Even better, the final name only stuck because the alternatives ran into problems.

The tech company says the team had considered names like RadioWire and PAN, short for Personal Area Networking, but one was too generic and the other ran into issues, leaving Bluetooth as the only real option.

Which means one of the most recognizable tech brands in the world survived by accident, and ended up with a hidden meaning that’s way cooler than anyone expected.
