Very well put and said and put, overnight ratings these days in this era of modern TV consumption, are just an outdated model, that does not give a true representation of how a show is doing.
To get a true idea, you need to look at multiple sources of data, rather than just the one like on the old days.
So for WWE, you need to learn how k at Network subscriber numbers, YouTube views, and subscriptions, twitter followers, and a whole host of other things before you can begin to judge if they are a succes or not.
Just looking at ratings and saying, oh it is 1.88, or 10.88 is totally meaningless, and doesn't mean anything to anyone these days, so I don't see why they are even brought up or discussed, as they do not give be a true representation of a shows following.
Most people pick and choose when and where they watch a show, the era of watching a show when the TV companies tell you to, is either at an end, or is very shortly coming to a close.
Look at how successful Netflix has become for example, there you can watch whole series whenever and wherever you want, there are no schedules there, and that is how more and more shows will be like I think.
There really is no point to actually having a TV schedule these days, shows should be available as soon as they are filmed and "in the can" so to speak, what is the point in holding them back?
Just do as Netflix does and put a whole series out all at once, rather than drip feeding the audience, and making them wait once a week to watch a show, that is such an outdated model.
