I have never owned a TV. I've seen how that stuff gets made, and that's more fun sometimes. Unfortunately, there is a very heavy editorial bias in favour of the sponsors' interests. I have, however, read Jerry Mander's "Four Arguments for the Elimination of Television" and they are really good ones.
Thanks to YouTube, I have watched most of The Big Bang Theory, and was appalled at the technical error in engineering that got by their science expert. The whole thing is almost an infomercial for the various pastimes of the cast, rather than an accurate depiction of geekdom. When has anyone on TV been short of money, had to wait for a computer, or had trouble parking?
