"It was vulgar, offensive, and insulting, not just to women and African-Americans but to anyone with a sense of common decency," said John Hogan, president and CEO of Clear Channel Radio. "We will not air Howard Stern on Clear Channel stations until we are assured that his show will conform to acceptable standards of responsible broadcasting."

Clear Channel has some 1,200 radio stations in the U.S., and Stern's program has been aired by its stations in six markets – Fort Lauderdale, Orlando, Pittsburgh, Rochester, San Diego and Louisville.
