Personally, putting aside e-commerce transactions (ebay etc), I did my first dollar on the internet by promoting Udemy courses on a blog I created yeaaars ago: http://elearnhero.com/. So the very first time I made money online was through affiliate marketing !
My first $ was a freelancer.com job building a desktop app to open the clients webapp.

2012. I was 16 and used to in sell game items from an online MMO called Runescape. But my was first real business transaction was a blog I made while in college that I ended up selling to a print magazine. I think that was my first serious amount I made.
