For years, tech companies have been striving to make highly sophisticated products that replicate or supplement the real world. But 3D-TVs have officially failed and augmented reality is still struggling to become part of our daily lives; meanwhile lo-fi is having a moment in the form of pixilated graphics and archaic web design. Teens in particular seem to be drawn to the counterculture movement (surprise, surprise).

Political marketing to young voters is big business. One report suggests that parties spent more than $100 million marketing to youth groups in 2010. And it's no wonder why: Politicians who want to win the White House in 2016 need to engage teens-and they need to do it soon. After all, today's 15-to-19 year olds will help elect the next president.
