How Do You Make a Profit Online?

I know youtube AdSense plus iTunes but are you making do you get sales or commissions from like Pandora and Spotify or anything else online or is it pretty much those two major things no. I also have two businesses that um one is a card game that I co-sided with my cousin that we invented together and we just have a website for that and we sell it so that brings in a nice amount. And then there's at the start of this year I started this badge thing it's kind of like for scout badges but for adults called Lyskout which is basically a tumbler where every few days an old badge image appears.
