Q. Television (A.C. Nielsen) ratings?

STV+ provides daily ratings as well as weekly and season broadcast ratings. For weekly ratings click on ratings, then weekly, and then keep changing dates. Ratings go back to 2011.

USA Today published a Nielsen ratings chart in its Life section (Section D) each week through September 20, 2017 entitled "Prime-Time Nielsen Ratings", this chart did not appear on the same day each week, so you need to check each day's paper to find the weekly chart. Databases containing the text of USA Today do not include the Nielsen ratings chart due to its format. 2009-2017 is included in ProQuest Digitized Newspapers.

For the period prior to 2009, use Broadcasting & Cable (Firestone - Oversize HE8689 .B79q). 1993-2000 is available in the ProQuest Entertainment Industry Magazine Archive (search Nielsen Ratings).  For 2001-February 10, 2003 use ProQuest Central.  Online equivalents after this period omit the charts so must use the paper.

Nielsen Media Research provides free brief demographic information on the latest "Top 10" television programs for different groups: Broadcast TV, Cable TV, Syndication, African Americans, and Hispanics. We have not been successful at getting details from A.C. Nielsen over time due to the proprietary nature of their business.

Each week's Nielsen Ratings are also available at Futon Critic.
    
The annual publication International Television & Video Almanac in Firestone stacks, call number HE8675.I66, also had ratings information. Ceased in 2014.
