The final week of 2008 was an odd one for the evening newscasts. NBC Nightly News finished first in Total Viewers and the A25-54 demo, but was based on a four-day average (only excluding Wednesday).
CBS’ ratings are based on a three-day average (excluding Wednesday and Friday) while ABC’s are based on a two-day average (excluding Wednesday, Thursday and Friday). During ABC’s two days, David Muir filled in for Charlie Gibson.
