NBC alone had over 20 million opening ceremony viewers this year (TV + Peacock streams)[0]. TV is a huge huge part of US culture. See also the Super Bowl, which just happened today.

So maybe not most, but a lot.

You're surprised sports in America has high viewership? Yes, the #1 reason people still have cables these days is for athletics.

You obviously don’t understand the role of sports in American culture. Or how the major television networks operate.

Sports events sure, opening ceremony? They are just going to get highlights on YouTube mostly.

This is making a remarkable assumption about a vast population. I know everybody in my family watched the opening ceremony on TV. Are you just making guesses?

According to the weekend ratings, 21.4 million Americans watched the opening ceremony on NBC directly.
