Mobile ad network Millennial Media has teamed with Digiday on a spcial report, looking at the state of the mobile app market, and expectations for next year.  The data offers some interesting insight as to the direction in which the mobile market is headed, especially as we see hints of mobile browser app adoption effecting consumer interaction with mobile apps themselves.

Among publishers and dvlopers, the iPhone, Android, iPad, RIM and Windows Mobile devices unsurprisingly dominated the most used charts, with the iPhone topping out at 30% market share, and Android creeping behind at 23%.

The anticipation around Windows Phone 7 is also picking up steam, as the upcoming platform is tied for second place for areas of developer interest around new OS’s.  Android holds a strong portion of this market, at 29%.  While the iPhone only gets a sliver of this pie, it’s been available to developers for years now, and is considered less for new areas of interest.

Revenue-wise, 31% of surveyed publishers anticipating significant growth in 2011, expecting their apps revenue to increase 100% or more.  Seventeen percent expect 50% growth or higher, with only 10% expecting their revenues to stay flat.

The report goes on to recommend the top five things to consider before building an app.  Reach, demographic, better branding, ease of use and a higher sales potential are the things advertisers and publishers noted when they planned their mobile strategy, which has become a vast and varied land.  Advertisers in particular looked at reach, targeting and cost per download.

The report also mentioned the verticals that are seeing the most branded applications, and they are in line with the trends we’ve seen throughout Millennial Media’s monthly findings.  Between 2009 and 2010, CPG worked its way up the chart, from the #5 spot to #1, while Entertainment fell from the top position down to #4.  Retail also saw growth from last year to 2010.
