Mobile marketers are entering the golden age of mobile marketing when it comes to targeting and connecting to teenagers.

Earlier this year when Piper Jaffray published its Taking Stock With Teens report, the hottest trends and purchasing preferences among U.S. teenagers were brought to light.

In the mobile device category, smartphones are hot commodities, with Apple’s iPhone leading the way. 91% of teens, the study’s findings reveal, are likely to purchase a smartphone for their next device.

That’s up from 86% last spring and 90% last fall.

As of November 1, 2013, it’s clear that many of the projections and expectations expressed earlier this year by Piper Jaffray and others have begun materializing.

Nielsen’s Q3 mobile report published this week reveals that 65 percent of U.S. phone owners now use a smartphone. Specifically, 70 percent of mobile usage in the 13 to 17 age range is now conducted with a smartphone.

For marketers, this means that it has never before been easier to effectively and responsibly target teens and young adults with relevant messaging through everything from SMS and video ads, to in-app content and even native ads.
