When the way of consuming the medium changes, the message it carries changes as well. The reason public broadcasting is so well loved and "special" is that it was something collective (out of necessity). If I don't like charcircuit, I can find a youtube video declaring charcircuit a dangerous enemy combatant. When you are the only game in town, there was a sense of making it somewhat "casual" and we got things like bob ross and mr. rogers neighbourhood.
