Twitter series on how companies earn money.

I am going to post about how different companies earn money. This is going to be almost like a Today I Learned (TIL) kind of thing but the topics are going to be about the business model of varying online companies. I am going to do this for my own learning but I thought it might help other indiehackers spark some ideas. I am also doing this to possibly gain a few more followers and eventually promote my own side project. What are your thoughts? Would a bite sized tweet about how a company earns money be interesting to you?
