This time last year, Peter Dille was SVP of marketing for Sony Computer Entertainment America.

But demonstrating the accelerating shift in power between various parts of the industry, since September, he's been chief marketing officer of Tapjoy, one of the key innovators in mobile gaming monetisation and discovery.

We dropped in to get his take on the past, present and future.

PocketGamer: What do you think was the most significant event for the mobile games industry in 2011?

Peter Dille: I don't know if it was a single specific event, per se, but I'd say the most significant trend that happened in the mobile games industry was the continued growth of Android and the maturation of its app ecosystem.

Ever since Android overtook iOS for mobile operating system market share in late 2010, the platform's growth has continued to skyrocket. Android ended September of this year with a 44.8 percent market share in the US (according to comScore), with Apple second at 27.4 percent.

The real sea change, however, came in October, when Android overtook iOS as the market share leader in app downloads as well, when it had 44 percent of all mobile app downloads compared to iOS's 31 percent, according to ABI research.

With a much larger user base compared to iOS, Android was bound to take over this crown, but it goes to show how big the demand is for mobile app installs on Android. It's trends like these that make developers turn their attention to Android.

What was the most significant event for Tapjoy?

In November, Tapjoy launched a new product, the Tapjoy Personal App Marketplace, which marked the moment we became a direct-to-consumer company as well as a leading B2B company.

Previously, Tapjoy operated behind the scenes and our value-exchange engagement ads were found within our partners' apps. With the new Tapjoy Marketplace, we created a direct-to-consumer mobile web portal where consumers could come to find, share and engage with mobile apps.

We're just getting started delivering on this vision to change how consumers discover apps so look for some great things in 2012. In the meantime, we are very proud of the service as it represents an entirely new way for consumers to, as it says on our homepage, "love the apps you have and find the apps you'll love."

What was your favorite mobile game of the year?

As someone who came to Tapjoy and the mobile space from the console gaming world, I've always been a big fan of Duke Nukem, and so I was thrilled to see Duke Nukem 3D come to Android. It's a classic game with a new twist, and to be able to play it on the train or when I have a few minutes to spare is awesome.

Duke Nukem 3D is one of the first games that Tapjoy helped bring to Android via our Tapjoy Android Fund, which helps identify, develop and market select games for Android. Another one of my favorite games was Glu's Gun Bros. Glu's more recent entrant, Blood & Glory, is pretty cool too.

What do you predict will be the most important trends in 2012?

I think the Android app ecosystem will continue to mature by giving developers all the tools they need to grow and monetise their apps more effectively, and providing consumers with less friction in the purchase process - which is really the last hurdle it needs to clear in order to completely challenge iOS. So you'll see advancements in IAP, alt-pay and other features in order to help developers generate increased revenue.

Another prediction is we'll see ad spending in mobile start to catch up to how much time consumers are spending in the medium. Apps represent a powerful new media option, and consumer engagement is at unprecedented levels. The brands are starting to take notice and the dollars will follow.

And finally, I think this will be the year that HTML5 makes its presence felt as well, giving developers a fantastic cross-platform solution.

What's your New Year's resolution and what resolution would you enforce on the industry?

Aside from the personal resolutions we all make and don't keep?

Professionally this year I'm looking forward to leveling out the learning curve in mobile - this new category I jumped into. It's a very exciting business and incredibly fast-paced, probably even more so than other technology categories I've been part of. I often still feel like the newcomer but that's happening less and less so I'm eager to continue to learn so that's completely in the rear view mirror.

From an industry perspective, I'd like to see the mobile industry come together to create common standards that address consumer privacy issues.

Tapjoy has always taken the approach that protecting user privacy is one of the most important things we can do, and we would never share anyone's personal data or disrespect it in any way. As the industry grows and matures we would hope that everyone else within the space - from app developers and publishers to mobile advertisers and ad networks - would resolve to act very responsibly and transparently in regards to user privacy.
Thanks to Peter for his time.
