Network television is enormously expensive and entirely paid by ads without knowledge of the viewers. Instead they make assumptions based on surveys of demographics and manage to be very profitable. I wonder if you could make a comparison of ratings of a TV show to active users of a website. For example: is Twitter the equivalent of daytime TV, or multiple series-finale-of-Friends per day. *edit: it looks like they are the equivalent of 0.8 Friends finale / day. 41m daily active users vs 51m viewers of the Friends finale.
