Answer 1

Well no one “produces” internet for one. It’s a service, not a product.

Basically most of the internet traffic on the earth passes through undersea cables having huge bandwidth capacities. These are divided per country. The country government further divided the network spectrum and sell it to small companies. The small companies called ISPs then sell it to the end user.
