In the 10th century, a Danish king called Harald “Bluetooth” Gormsson, named after a dead tooth in his mouth, would go down in history as a ruler who united Norway and Denmark. Close to a thousand years later, his name would be pinched and applied to a technology designed to kick cables into touch.
The iconic Bluetooth symbol also has Viking lineage. It’s a combination of the Nordic rune letters for H (ᚼ) and B (ᛒ), Harald’s initials.
The technology was developed in the early ‘90s by Ericsson. The idea was to use radio frequencies to connect electronic devices, disposing of the need for wires.
By the end of the decade, the first consumer product utilising the nascent technology was revealed. The award-winning device was a wireless headset, and the pathway towards Bluetooth ubiquity had well and truly begun.
