I've been around long enough that my experience precludes everything but telephone, TV, and radio. That said, there were no privacy concerns at all other than local storage of postal mail and/or other hand-delivered papers or photos. The thing about "growing up" in today's world is, you NEED to be constantly vigilant about EVERYTHING you do, because it ALL has ever-lasting repercussions whether you like/want it or not. This is the ultimate trade-off of living in the digital world, privacy has now become an illusion of fantasy. The only way to obtain it is to completely and totally remove one's self from the digital world, which of course, no one is willing to do!
