Yes, I create 3D animations that seamlessly loop, so I just loop them to be 30-60 minutes long and have been uploading them to YouTube for the past year. Once I got monetized, I was earning $2-$3 a day. I decided to throw mid-roll ads on them every 5 minutes, and now I'm earning $8-$12 a day. I'm getting about 3000 views a day. It's not a lot, but it's surprisingly consistent, and I only expect those numbers to grow over time. I can't say I feel the same about the stock websites.
