Pandora commands higher than average ad rates. Remnant (which is bargin basement inventory) is somewhere around $5cpm and I don't think they sell to networks for display to keep demand high. It's actually hard to get inventory there unless you are a premium buyer. For those of you who don't know or care much about online ads, all this basically means is that almost every other publisher (Huffpost, whatever) would kill to Pandora's rates. The fact that they aren't incredibly profitable shows how tough the business is. God knows how Grooveshark makes any money.
