NBA Finals Ratings (1998-present)

Below are the Nielsen ratings for the last 25 years of NBA Finals, back to 1998. Household (HH) ratings, 18-49 ratings, viewership, and M18-49 ratings have been provided for each year. The color-coding works exactly how it works in the World Series post with each metric compared against each other: i.e. all HH ratings are compared, and all 18-49 ratings are compared. The greener the chart, the better the ratings. Note: I've included both the undercount viewership and revised viewership for 2020 and 2021; this post will be updated if/when additional data is located and/or to add older years.
