Here, I'll just pass along a few slides that particularly caught my eye, on the general theme of how our interaction with media is evolving. The old model is about turning a station on or off, or going to a certain website to read what's there. The new model is toward greater interactivity. For example, here's a figuring that starts with the VCR and cable television back in the 1970s, as way in which users began to exercise more control over media, and points to the many ways in which this trend has expanded.
Of course, this use of media isn't just about watching cat videos. It's more and more using mobile devices like smartphones or tablets for many purposes: news, directions, events, and more.
