Second, I have Googled looking for total radio market gross billing with no luck. Do you know if that is publicly available online?
The IE bills poorly because so much of the audience goes to LA stations, with the local commercial share being around 30% to 35% of the total. Thus many agency accounts just buy the LA stations and don't buy the IE.
LA has a perception of being a "more radio" town, partly due to the fact that New Yorkers use so much radio-less public transportation with consequently lower in-car usage. Climate, lifestyle, etc., also contribute.
Market billing data is sometimes published in local newspapers or business journals when BIA releases some data around March-April of each year. There used to be books that showed market profiles, such as Duncan's American Radio market books, and which were reasonably priced, but I know of none now.
