Posted by Brian Aubert, Account Director New figures from Nielsen show that mobile data use by teens is up fourfold. Additionally, 43% of teens primarily get a cell phone in order to text. This means that QWERTY keypads are one of the first things teens consider when picking a mobile device. Thus, the Blackberry Curve is surprisingly popular among teens—more popular than the iPhone. And once teens get their QWERTY keypad phone, they’re not just using it for texting—they’re downloading apps. In developing mobile applications for teens, advertisers should therefore think beyond the iPhone and ensure that their apps are compatible on multiple devices, like the Curve.
