Anode always have been positive side and cathode negative side. They
have been used in reverse bias in some circuit such as across coil of
relay (to allow residual current to drain across diode rather than
through the relay driving circuit) and in cheap voltage regulator
circuit (zener diode is almost always used in reverse bias)
