The 15 Most-Watched TV Programs of 2018

If nothing else united us this year, these shows did.

There's no denying that Americans love television. According to the Bureau of Labor Statistics, adults in the U.S. watch an average of 2.8 hours of TV each day.

With hundreds of channels to watch and streaming services to sift through, it's rare these days that everyone you know is tuning in to the same thing. But it does happen.

There were moments in the 2017-2018 TV season where Americans were glued to the same celebrations of athletic prowess, on the edge of their seats together for a gripping police procedural, or collectively celebrating the return of a '90s favorite. Here are the 15 most-watched programs of the past TV season, on average, according to Nielsen.

Super Bowl LII

The Big Bang Theory

This year, The Big Bang Theory proved that its fanbase remained just as dedicated as it was when the show premiered more than 11 years ago. According to Nielsen data, the sitcom was the most-watched program of the 2017-2018 season after the Super Bowl, with an average of 18.634 million viewers tuning in. And while the show's numbers are certainly nothing to sneeze at, The Big Bang Theory was at its peak in its ninth season, when it averaged 20.36 million viewers.

The much-anticipated Roseanne reboot scored outrageous viewership for ABC in March, averaging 17.815 million viewers per episode. But then, the show was canceled in May after Roseanne Barr likened President Obama's former senior advisor, Valerie Jarrett—an African-American woman—to an ape. However, Roseanne was once again rebooted, this time without Barr in tow, as The Conners. It premiered on October 16, bringing in 10.56 million viewers.
