Texting primary mode of communication for teens, survey finds

If you've been flustered about your teen's obsession with texting and cellphones and the subsequent drain on your wallet, you aren't alone.

A report by Pew Research Center's Internet & American Life Project, found that daily texting or text messaging skyrocketed among American teens.

Thirty-eight percent of teens were texting daily in February 2008. That shot to 54% in September 2009. If you think those numbers are making cell phone companies grin, here's more reason for them to cheer. Half of teens send 50 or more text messages a day, and one in three send more than 100 texts a day.
