Computer screens surpass radio as second most common media activity.

Here's a media quicky - the average American is exposed to 61 minutes of TV ads and promotions a day. Some may think that amount seems excessive. Others, like me, would say it falls short. Adults are exposed to screens - TVs, cell phones, GPS devices, for about 8.5 hours on any given day, according to a study released by the Council for Research Excellence, an entity created by Nielsen Company.

A couple of findings that won't be very surprising - TV is still the dominant medium for both media consumption and advertising, and computer screens have now surpassed radio to take over the number two spot. Print media ranks fourth.
