Touche, but that article is based on a study done in 1969, and programing back then did not offer the thought provoking shows that are on now. OK, so 90 percent of the shows are brain-deading these days. My point, it depends on what you watch. In the '60s, you could not turn on the TV and watch channels dedicated to learning, thought provoking programing. Avoiding generalizations, and you will find there is good on TV.
