I read this

In May, YouTube became the most popular channel on TV compared with any other streaming platform or network, and nearly 45% of YouTube’s viewership in the U.S. happens on televisions.

About 90% of my youtube watching is on a TV - and the balance is really just revisiting and sharing stuff I think is worthwhile. Never been a big thumbs up person on a video (sorry creators) .. BUT I wonder how such a shift hits that particular metric - since that action - while not impossible - is quite a bit more finicky when using. TV to watch.
