Many years ago, I remember seeing a blue haze coming out of most house windows as I was driving home from work in the evenings. It seems like just about every household had the television permanently switched on. However, this has become quite rare lately. Either folks have invested in thicker curtains or they are deliberately watching less television. Could it be that many folks have made the wise decision and are switching off their televisions? I've even heard of folks that are off cable or satellite tv, something that was all the rage a few years ago. Or have they simply replaced tv viewership with the internet, online streaming and social media?
