Mystery behind the name : Bluetooth



Bluetooth-PNG-Free-Download.pngWe all use Bluetooth. It’s on your cell phone, earphone, laptop, eve in your car. We use it to link up 2 devices so they can connect wireless-ly. I always wondered what kind of technical term is that. We all know Blu Ray – a device with Blue ray (laser) used to read/write to the disk. Infrared – uses infra red to connect. What kind of ray is in Blue tooth?

Recently, while I was browsing something else, came across a little anecdote about the name. Would you believe, it may be referring to blue teeth a king had due to eating too many blueberries or due to tooth infection!

When one of the founds of Bluetooth, Kardach from Intel, was looking for a name for the new technology, had been reading a book about Vikings that featured the reign of Harald Bluetooth (Scandinavian Blåtand/Blåtann), whom he viewed as an ideal symbol for bringing competing Danish tribes together, as he explained:

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.

Apparently, the name stuck when he couldn’t register the technical name for it in time.

The bluetooth logo is a combination of couple of Rune characters as well, as Wikipedia article puts it:

The Bluetooth logo is a bind rune merging the Younger Futhark runes Runic letter ior.svg (Hagall) (ᚼ) and Runic letter berkanan.svg (Bjarkan) (ᛒ), Harald’s initials.
