Its a badly kept secret that their overall audiences have been shrinking, which is why they only ever give ratings in terms of percentages. A large percentage of a shrinking market is ok, until of course the market gets below a certain size.
Note this does not include the ABC, which is government funded. That network takes risks, always shows series in order, and even has a great streaming service.
