*- The number I saw for CBS came before finals were available on the last day of the season, and it wasn't certain whether it'd end up being a 3.9 or 4.0. So I went with 3.95, which is likely more accurate than the other two numbers would be.
*- This was the WGA strike year, which shortened the seasons of most scripted shows. This was felt most on ABC and CBS as they have the heaviest reliance on scripted series.
The networks' hierarchy is exactly the same in Live + SD, but each net's number is about 20% lower. My Live + Same Day numbers for 2011-12 say Fox 2.7, CBS 2.5, NBC 2.1, ABC 2.0.
