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.
