Media Life: A new study from Divimo, a network with multiple YouTube channels based in Europe, finds there are marked differences in what young and old people watch on YouTube, though the top draw for men and women is surprisingly similar. “The digital submergence of our youth makes them more capable to live out these interests on the web. Older viewers are much more cautious, and still keep many of their hobbies offline,” according to the study, which examined 1,157 YouTube channels.
