Franken also said Air America is the #1 provider of streamed audio online, with 6.5 million "distinct" listeners. In addition, he reported that KPOJ Portland's in-house research showed Air America had increased their cumulative audience (number of people who have listened at least once during a one-week period) by nearly five times.
I also have it on good authority that, even though Air America was only on the air a couple weeks, WNTD Chicago had the best "Spring Phase 1" ratings in that it had had in the last 12 months (though that was a pretty low bar). ("Spring Phase 1" means the average ratings for February, March, and April combined. Arbitrends don't give figures for single months, they give figures for three-month phases. You have to run the raw numbers through a program called Maximizer to get single-month numbers -- that's what Inside Radio meant by "extrapolated" April numbers.)
Plus, on The Majority Report, Sam Seder mentioned that they had increased their listenership by 170%, moving WLIB from #20 to #10 for their daypart.
All this means that, even if April was just some peak-of-interest fluke and AAR were to fold tomorrow (which looks very unlikely now, and not just because of the ratings), there's a huge, proven audience for liberal talk that station managers are going to notice. My larger hope for Air America has always been that it would prove that there's an audience for liberal talk and help other liberal hosts, like Arnie Arnesen and Ed Schultz, get more syndication deals. Liberal radio should grow beyond Air America, just as right-wing radio is far more than just Rush.
