CSI: Crime Scene Investigation
Until 2012, CBS ranked in second place among adults 18–49, but after the ratings declines Fox experienced during the 2012–13 season, CBS was able to take the top spot in the demographic, as well as in total viewership (for the fifth year in a row) by the start of 2013. At the end of the 2012–13 season, the tenth season of "NCIS" took the top spot among the season's most watched network programs, giving CBS its first top-rated show since the 2002–03 season, when "CSI: Crime Scene Investigation" led Nielsen's seasonal primetime network ratings.
