America loves its football, but the top action on TV this season wasn't on the field — it came via CBS' still-potent NCIS.  In its tenth season, NCIS managed to beat NBC's Sunday Night Football as the year's No. 1 program among total viewers.

CBS' The Big Bang Theory was the highest-rated comedy this past season, while AMC's The Walking Dead broke into the Top 10, a rare feat for a cable series. Even more impressive, besides football, The Walking Dead was the No. 1 show of the season among adults 18-49, followed by The Big Bang Theory.

Among new series, CBS' Elementary was the highest-rated in total viewers, while the Fox thriller The Following led all freshmen in the 18-49 demographic.

CBS aired 12 of the top 25 shows, more than any other network. CBS has such an embarrassment of riches when it comes to hit series that freshman drama Vegas was canceled even though it made the top 25 list. (To be fair, Vegas did not perform well with adults 18-49.)

Meanwhile, how big is A&E's Duck Dynasty? So big that the reality sitcom attracted more viewers this past season than all but the top 3 scripted comedies on television.
