Disc jockey Don Imus, whose career was made and then undone by his acid tongue during a decades-long rise to radio stardom and an abrupt public plunge after a nationally broadcast racial slur, has died. He was 79.

Imus survived drug and alcohol woes, a raunchy appearance before President Clinton and several firings during his long career behind the microphone.

But he was vilified and eventually fired after describing a women's college basketball team as "nappy headed hos."
