Then as the article moves on, it says TV ratings are sinking too, by double digit percentages. But why?
Company's use the Neilson Rating system.
So, Many TV series themselves were doomed thanks to Neilson, despite having millions of loyal fans.
Neilson's Rating system completely ignores DVRs, wether your watching Live, Delayed, or Replayed.
take into account how many cable and dish providers are phasing to only putting out DVR boxes (just disabling record permissions for those that dont pay for DVR.)
You get a sudden decrease in ratings.
For Example: Heroes went from a 3.5 Average Rating for the season to a 1.35 for the Final Season, but when they added DVR/Delayed/Replayed (aka Live+7 Day Rating)ratings went back up to 3.8-4.1 Marks.
The Live Ratings is what companies look at, and the reason why Heroes was finally cancelled.
