I haven't seen the final numbers for the season finale yet, but I did come across this very interesting article:
CBS Finishes Season Number 1 in All Key Ratings CategoriesTo say
Elementary has been a success for CBS this season would be an understatement, as the statistics presented in the article clearly show.
(Also notice that over the course of the season
Elementary routinely gained an additional 3 million viewers each week once the Live+7 DVR numbers were factored in - which is why, as I said last week, it's quite possible that
Elementary's finale ultimately came in ahead of
Scandal.)
