Let's do some of that high level math called division.
Limbaugh = $200 million per year.
Beck = $100 million / 5 years = $20 million per year.
A nice little chunk of change, but not a lot of pressure on Rush. Also, many of these contracts are for the whole show and not for just the main host, so it pays for the studio, call screener, sidekicks, replacement hosts (lots and lots of those for Rush lately) and anything else it takes to run a show.
LoL.
