Exclusive research released by DM2PRO.com and Quattro Wireless at the digiday:APPS summit in Los Angeles today revealed that, among advertisers or agencies who have worked with mobile apps, a third expect their mobile apps budgets to increase by more than 75 percent in 2010, some by greater than 200 percent.

As a reality check, more than half of the more than 234 advertisers, agencies and marketers who participated in the survey, said they haven’t yet developed mobile or social apps. But even among these skeptics, 65 percent said they plan to develop mobile apps in 2010, with iPhone being the clear winner in terms of platform of choice at 91 percent (followed by Android at 39 percent, RIM at 33 percent, Palm at 19 percent.)

Among those who have already developed apps, the leading platform for which those apps are developed is still Facebook. But iPhone is a close second, showing that marketers are keen to follow audiences wherever they live or work or interact. Branded community sites are the next most popular venue for apps, then MySpace. Android lags this list at just 9.5 percent, though it’s more popular in the developer community.

For publishers who’ve developed apps, the inverse is true: iPhone leads Facebook. Greater than 35 of publisher’s who took the survey say that, even in today’s tight times – expect their mobile revenues to increase by greater than 50 percent.

Those are just a few highlights of a much longer study that will be released on the collaborators’ Web sites next week. Melinda Gipson, publisher of DM2PRO.com, said, “State of the Industry Surveys are developed alongside our targeted digiday events to give digital media and marketers insights on what their peers are really doing in that environment. We tap practitioners in the space to expand our reach and understanding of what professionals need to know to plan and execute their programs profitably.”

She added, “Quattro Wireless, with its deep reach into the mobile developer community, was the perfect collaborator for this research because developers will exercise substantial influence on the way this market goes.” Does more Android mean less RIM? When will Android catch up or even pass iPhone in terms of reach? How are apps being monetized and promoted?

Developers who work for advertisers or agencies said they expect mobile development budgets to increase sharply, while their counterpart social-only developers report their spending for next year should be roughly flat. At a time when online advertising is inching downward, 58 percent of agency mobile developers expect increases of more than 40 percent.

The most engaged brand categories with apps, according to active respondents who represent them, are: CPG, retail, automotive, entertainment, financial, health/pharma, media, tech, B2B and beverage. Lagging brands – those represented by advertisers or agencies who haven’t yet developed apps, in order of response by least engaged: B2B, health/pharma, media, retail, financial, entertainment, travel, CPG, tech, and auto.
