Did you know that the name of Bluetooth, one of the most significant inventions of modern times, owes its name and logo to a Viking-era king who had a bad tooth?
Sven Mattisson, one of the engineers who was behind developing Bluetooth, also revealed that the name was decided over beers.
In an interview with news agency AFP, Mattisson said that he and Jim Kardach presented their ideas at a seminar in Toronto in late 1997.
"Jim and I said that people did not appreciate what we presented," the 65-year-old said.
