Why is a widely used app named for a tenth century Scandinavian king?
by an old friend from “The Fray” Claude Scales
Your smartphone, like mine, likely has the logo at left on it somewhere. I knew that “Bluetooth” was the name given to an ancient Scandinavian king, but had no clue why the app was named for him. Now, thanks to Rick Spilman in The Old Salt Blog, I know the reason.
The logo is the Viking rune of King Harald “Blåtand” Gormsson, “Blåtand” is “Bluetooth” in English. The rune is a “bindrune” that combines the runes for “H” and “B.” Bluetooth was a Danish king (940-981) who united Denmark with Norway. According to Spilman, an engineer who was heavily involved in developing the technology that became Bluetooth, Jim Kardach, was responsible for giving it that name. Spilman gives a helpful link to an article by Kardach that explains the history. It’s a long, complex, but amusing story, including an account of “a pub crawl through wintrily [sic], blustery Toronto.” Kardach sums it up as follows:
When asked about the name Bluetooth, I explained that Bluetooth was borrowed from the 10th century, second King of Denmark, King Harald Bluetooth; who was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link.
So, sometime soon, I will raise a glass of Aquavit and toast Harald Bluetooth, who inspired my ability to play WQXR on my stereo sound system from my smartphone.
A friend of mine worked on the Bluetooth standard at Microsoft maybe 20-something years ago. It was a really crappy protocol, but it had to work with really limited hardware. It dropped packets. It dropped the connection. It introduced static into audio. I have no idea of how given that it is a digital protocol. I kept trying to use it for over a decade and giving up in disgust each time. Finally, maybe six or seven years ago it became usable.
It’s still kind of crappy. I mainly use it with my Airpods, and I’m constantly having to reconnect it to my Mac or my iPad or my iPhone since it’s a one-to-one protocol. Since it’s digital, you’d think I could just connect my ‘pods to all three sources and let it sort it out. You can do that with wires and a few resistors. You’d think it would even easier with software.
