I read somewhere where magazines can only have so many subscribers without it costing them more to publish than they make. Their other problem is that they must show evidence of a certain amount of subscribers in order to sell ad space.
I have noticed that all publications as well as radio and TV are starting to have almost as much advertizing as show or content. There was a time when I was dumb enough to think that because we pay for cable that it would have no commercials. What planet did I think I was on?
