L.E.K.'s Media Consumption Survey polled over 2,000 consumers, asking them about their general media "diet," from ereaders to online video. The results? Ereaders are big, older folks are into the Internet, and online radio is finally reaching the mainstream. Most of this isn't huge news but the statistics are pretty striking. For example: 32% of users listen to an average of 5.8 hours of Internet radio a week, a huge jump. iPod owners consume 8.9 hours of media per week while e-reader owners consume 18.2 hours of new media per week. That means e-readers have a captive audience. Folks aged 50-64 use 8.3 hours of Internet per week compared to 24-39 year olds who use it for 6.8 hours.
