Last week I had the opportunity to provide a guest blog post over at Mobile Marketer about the future of Mobile Ad Networks. You've probably seen a lot of columns recently about online ad networks, such as here and here. So will this be another example of mobile emulating the web? In many ways, yes, but ad networks continue to play an important role. Today big brand publishers dominate mobile advertising with the most trafficked, sticky sites. As these publishers begin to realize revenue from mobile advertising, they will begin to bring ad sales in house. So where does that leave the ad networks? Read more about it at the Mobile Marketer blog and leave comments here or there. I look forward to continuing the discussion.
