What is the Bluetooth symbol?
The Bluetooth symbol resembles two and a half triangles pointing to the right. The symbol is a bind-rune, which is the symbol for "H" and "B" which is short for Harald Bluetooth, a Viking king from Denmark between 958 and 970 that help unite Denmark and Norway. It is named after Harald Bluetooth because the Bluetooth technology was designed as a universal wireless technology that can be used by everyone.
