Rewind to the year 958. No, really. The name comes from Harald “Bluetooth” Gormsson, a legendary Viking king of Denmark and Norway.

Why “Bluetooth”? One story says he had a dead, blue-ish tooth. Another suggests he was just really good at eating blueberries. Nobody knows for sure—but the nickname stuck like glue.

Here’s the kicker: Harald was a unifier. He brought warring tribes together under one banner. A thousand years later, tech engineers decided their new wireless standard needed to unify devices in the same way.

The Eureka Moment in a Bar

Jump to 1996. Intel, Ericsson, and Nokia engineers are at a meeting in Toronto. They’re brainstorming names for their short-range radio tech. None of them love “RadioWire” or “PAN.”

Then an Intel guy, Jim Kardach, pulls out a history book. He’s been reading a novel about Viking kings, and he blurts out: “What about Bluetooth?” The room went silent.

Everyone thought it was absurd—and brilliant. A codename that sounded weird but perfectly captured the mission: connecting different “tribes” (phones, computers, headsets) without cables.
