RWN radio as a whole is on the death watch.
It may eventually go the way of LWN radio, and be gone completely.
However, Limbaugh himself has been nationwide for 25 years. He can be gone tomorrow and
he will be remembered as being WILDLY successful.
For nearly his entire duration there has been almost no place you can go to in this country, and not find him on a radio station.
He is still very popular, and is obviously taken serious enough to be quoted nearly on a daily basis by media such as the left wing spewer being quoted here.
Regardless of his ratings or popularity, he's likely to be calling it quits as far as the radio show goes, he's 64 and he'll be winding down one way or another.
He still has his bottled tea business, and now that he is children's author of the year, he has a very good future in children's books, in fact his third installment of the current series is about to be released.
