*Ratings are specified in the 18- to 49-year-old demographic and viewership in P2+.

A note about ratings: Ratings are expressed as percentages of Nielsen's estimated 114.5 million U.S. television households. The first number, the rating, is a percentage of households tuned into a specific program at a specific time.

The second number, the share, is a percentage of households with televisions in use tuned into that same program. For example, if a show obtains a 10.2/16, this means that 10.2% of all U.S. households tuned into the program at some point during the broadcast. Meanwhile, 16% of all households watching television during the time period viewed the program at some point. Ratings are broken down further by demographic, as networks sell advertising time based on the makeup of the audience.
