Skip to the ninth paragraph and you'll still get the gist. This one's about programmatic advertising. Which is helpful because that's all mobile ads are.
Ninth paragraph indeed: I actually clipped this quote before I noticed you had said that:
"Actually, the opposite is true. Programmatic is expanding because it allows advertisers to pay more for ads, and to be happy about the fact that they're doing it. We are in the midst of a multiyear transition in which it feels like ads are cheaper, but ultimately the cost of advertising is going up."
