I believe Tyler Cohen's "The Great Stagnation" arrives at a similar conclusion, but I'd like to see hard numbers. In regard to entertainment, it'd be interesting to see a nomalized total $/hr comparison of various activities. For example, compare a standard movie in a theater to playing Dragon Age. That'd be roughly $15/hr (adding popcorn) vs. (120 hrs game play / ~60$ for the game) ~$.50/hr. That seems impressive, but .50/hr is still much higher than the 0$/hr that free broadcast television offers. I'd be curious to know how all these different types of media consumption shake out in the long run.
