There seems to be an idea vacuum in the mobile advertising space. At least, that’s what you might glean from this chart provided by mobile analytics firm, Flurry.

The mobile audience is there, but the ad spending isn’t. At least, not compared to established media like print.
Ezra Klein’s optimistic perspective (which I share) suggests some of the rationale behind the disparity in ad spending in mobile versus print.
“The business model behind printed news might be dying. But the business model behind information is just transitioning.”
In other words, ideas (and media spend) exist in print, in part, because of a familiar architecture. Time spent by consumers in print may be waning, but the space is well known to CMOs, art directors, account managers, et al. The ad industry plays to its strengths, providing more ideas than the audience apparently has time or interest to consume.
But over in mobile, the space is still being invented. The rules are changing frequently. As The Next Web puts it, “Right now, consistency, standards and best practices don’t really exist on the mobile frontier.” How many media planners have more than a year buying mobile ad space? How many art directors have created more than two mobile ad campaigns? It’s simply not part of a routine yet.
It can be difficult to develop a wealth of ideas in an ever-evolving realm. But that’s also the best opportunity for ideas that define the new realm.
