I was about to say the same thing. How do they make money? Of course, I never go on Facebook or any of those other types of places.
Indeed, I’ve never even ordered or done business on the internet, other than about 15 years ago, when I was using Ebay.
I’d imagine they do it the same way as TV networks: ad revenue. People don’t realize that TV isn’t selling products to them; they (the audience) have been sold to companies as advertising targets.
