Highest Rated Oprah

In honor of Oprah's last show, The Oprah website has made a list of the 25 highest rated oprah shows ever. I find it very bizarre that none of the highest rated shows happened after 1994.... What does that mean? lol That her ratings have been going steadily downhill? Explains the ''final'' season. Here are the titles of the shows and dates:
