I like using You Tube to get instructions when I am not sure what i am supposed to do in a  situation
That's a good idea. You can learn to do just about anything from YouTube videos.
Yes . It must be very thoughtful of the three guys who created the service.
I bet they made a lot of money. I remember when Google bought YouTube. It was a big acquisition for them.
It costed google 1.65 billion dollars to acquire You Tube. That is a lot of money for sure.
I am pretty sure they will make a lot more than that in the long term. Have you tried YouTube Premium (used to be called Red)? You pay a fee and can watch shows without commercials.
No I have not. I prefer the free You tube as i get to view important ads.
It's amazing that prominent YouTubers can make a living just through their ads.
