There's an old saying in the entertainment business, which is 'controversy creates cash'. Rush Limbaugh may be a polarizing figure, and as hated in some quarters as he is loved in others, but he knows the value of causing a stir, and he's taken it to the bank.
The staunch conservative radio host has millions of loyal listeners who would follow him from station to station wherever he goes. His employers know that, and that's why they pay big money to keep him where he is, allowing Limbaugh to live a life of luxury. For all the offense his views have caused, he has shown signs of having a softer side. He was happy to send himself up during an appearance on 'Family Guy', and every year he takes part in a telethon to benefit the Leukemia and Lymphoma Society.
