Peter I am aware that most YTubers don’t make money. But it is possible. In fact I have recently been told that 2 of the videos I edited for a charity have just started to provide money to the charity from YT.
I don’t know how many hits that means they have received but even £1000 (100,000 rupees) is very welcome for an Indian animal charity.

I can give you another example: get onto any UK ATC forum and mention the Graham Hill crash, and mention certain commentary on ATC service found in some of the books written on that crash. You will get a nuclear explosion… Admittedly this is partly because these professions close ranks in milliseconds, but if you are talking about flying videos where ATC is an “unwitting participant”, here you go
