For today’s wired teens, tomorrow is mobile.

Finishing up it’s two-day convention in San Fransisco yesterday, YPulse National Mashup is a yearly event that brings together youth media and marketing professionals from brands, agencies, and the non-profit sector to share practices for reaching today’s totally wired youth. And this year’s findings were a rather obvious one for anyone walking around any school, mall, or other teen gathering place. Teens are becoming more and more mobile and cell companies, advertisers, and other media companies plan to be sure to capitalize on this.

And capitalize on it they will indeed be able to. It’s estimated that teens wield a whopping $200 billion annually in discretionary spending. Yep, you read that correctly, and it wasn’t a typo. Two-hundred BILLION. Today’s kids must be charging much more for lawn-mowing services than back in the day, or else get one heck of an allowance.
