Back in late March when the Air America radio network premiered, we heard all the doomsday predictions from conservatives who wanted it to fail. We haven't heard anything lately from those same folks who would now have to concede that liberal radio is fast becoming a success.

The network is now at 40 affiliates with reportedly more to come after the new year. They have also secured new financing and brought on Real Networks CEO Rob Glaser as their chairman. Also, Al Franken and Randi Rhodes have renewed their contracts with the network with Morning Sedition hosts Marc Maron and Mark Riley and others expected to follow.

The success of Air America really started when they moved from a model of purchasing radio stations to seeking out affiliates who wanted to air their programming. The shows themselves have also matured whereas when they started their flow was a little rough around the edges. With conservative radio getting more boring by the day as the hosts read the daily marching orders faxed to them by Grover Norquist, Air America and other liberal talk show hosts like Ed Schultz are seeing the fruits of their labor pay off.
