I've seen very interesting statistics - I may have them somewhere; I'm REALLY bad at computer use and so it's hard for me to save or find anything, :( - but the social fabric actually began to fray at the same time TV became available and widely watched. Every soical indicator - crime, divorce, sexual immorality, unwed motherhood, and some others - were at a basically flat line until the mid 50's. The watching of TV and all those social ills went up at the same rate at the same time.
The mass indoctrination of population? What are the values, beliefs, and philosophies of the small group of people who write the TV shows, produce them, and write the "news"? A tiny percentage of the population is feeding the minds of the vast majority.
BTW, I've had a TV a total of about 1 or 2 years in the last (figure it out) - since I left home at 16 (early 50's now.)
