In the short run, I think this discussion of how TV has become, on average, more complex and cognitively challenging, is reasonably good. In the long, run, though, an analysis of just TV fails to capture enough of"popular culture" to stand on its own. The narrative complexity which is cited here as a recent development reminds me more of 19th century novels; the narrative simplicity cited as the"traditional" TV fare reminds me of 20th century pulp fiction (detective, romance, western). Others may see more substantial connections elsewhere.
