Ad revenue from YouTube-worth chasing?

The significant revenue increase on my YouTube channel from my videos covering the Conor McGregor trial have been an eye opener.

I never saw YouTube as being of any significance from an ad revenue perspective. But I have to reconsider the situation now and think about whether I want to make videos for ad revenue as well as my usueal diet of business and law.

The key to such growth would be topical, trending issues or cases. And I would have to consider whether going into the political arena would be worth the trouble, too.

Perhaps I should try one or two and see how they perform. This is how I have built my YouTube channel, to a great extent: trial and error.
