Do you have to pay to watch videos on YouTube?
Some you do and some you don't, you do have to pay to watch movies though there will be a price on it like $1.99 or whatever for an hour
I'm not sure what this question is asking, but for the most part, you do not have to pay for anything on YouTube. It is free to upload videos, and it is free to watch videos. Those basic functions are free but there also are some other things you can pay for, such as promoting your videos by paying for an ad on the site.
YouTube makes its income from the advertisers who want to display their ads on YouTube on user-created videos. YouTube makes money when visitors click on advertisements or watch advertisements on YouTube because the advertisers invested money into their advertisements through a click-per-pay deal or a watch-per-pay deal.
