Back in December when Millennial Media launched their 2010 mobile ad predictions, they said that 2010 is not going to be the Year of Mobile, because 2009 was.  Advertisers asked us for more proof points on that assertion, but Millennial wasn’t able to share year end information at that time. 

Now they can.

This year-end summary is based on observed traffic, server log reports, and other sources on our network.  Since Millennial Media is the largest mobile ad platform, we anticipate much of this data is fairly representative of the industry as a whole.

Some Highlights

Brand business grew 756% (brands really embraced mobile in ’09, especially compared to performance advertisers)

Average deal size increased 353% year-over-year

Top Ten 2009 Advertising Verticals by Spend (this will likely radically change in ’10, with Pharma, auto, and retail leading the charge).

Non-U.S. impressions increased 117% year over year (Europe primarily drove this large increase)

Device Quick Stats

· 357% increase in Apple OS impressions

· 90% increase in RIM OS impressions

· Top 5 devices on the network (spoiler alert—three are BlackBerry devices)
