Howard Stern
Stern is the most popular and well-known of a variety of offensive radio hosts known generally as "shock jocks."  In spite of the crude content of his show, many radio listeners consider Stern's delivery to be far from the worst quality radio aired today.  His popularity has given rise to a number of imitation "shock jocks" who attempt to outdo Stern in terms of offensiveness and rudeness...but these imitators have found themselves with more troubles to worry about than listener ratings.  In 2002 rival radio hosts Opie and Anthony were fired from their popular radio show after they encouraged a couple to engage in sexual intercourse at Saint Patrick's Cathedral in New York City, then airing a running commentary of the act on their show.  Stern, his supporters note, has not gone out of his way to offend the general public in this manner.
