Savage has taken a pretty big nose dive, from 8 million listeners/week in 2005 to 5.5 million in 2014.
The big gainers have been Mark Levin, who didn't appear on the 2005 list and is at 7.25 million in 2014, and Glenn Beck, going from 2.75 million in 2005 to 7.25 million in 2014.
You are doing a apples and oranges... This is not the right way to look at it. In 2005 Savage had already an established show with Talk Radio Network was aired on 300+ stations with approx 9-10 million weekly listeners.
in 2012 Savage left TRN, and was off the air for 3 months. This new show with Cumulus started out less then a year ago on 200 stations with 3 million listeners (Talkers) and he is been steadily growing month to month.
