True, but for watching video? Is the need that common away from home/office/workspace? I get YT videos, which often don't need as big a screen, but movies and tv shows on a phone?

Have you actually compared the view of a phone that is inches away from you face to a Tv that is a few yards away from you?

Besides that, have you thought that everyone’s lifestyle may not be just like yours?

I don't watch tv a few yards away, but point taken people have different lifestyles and needs. I should have rephrased the context to be my surprise that the big phones came to totally dominate the market, when it makes them harder to handle and more cumbersome to keep on your person. I didn't think consuming content would completely trump that, not with the simultaneous rise of tablets. Choice is good.

Go to any public transport commuter city and the buses and trains are rammed with people watching tv in their phones

Your TV isn’t at least 9 feet away from you?

Only if I'm at someone else's place. I watch on a monitor two feet away.

You do realize how atypical that is, don’t you?

What? Watching things on your computer is atypical? These days, I'd argue owning a TV is atypical.

96% of households in the US own a TV

Are we really going to do the whole Slashdot meme “Do people still watch TV? I haven’t owned a TV in 10 years”.

I often end up watching TV on a phone when I'm on a bus/train. Though I'm not too bothered about the size.

Before quarantine many people watched videos only during commute as they were too busy working at work and housekeeping at home.

Movies, no. Casual TV shows, yes.
