It depends on where you live. I lived in a rural area so the nearest local isp was far enough away that it cost. The cds and floppies that constantly came in the mail didn’t charge though. There were a bunch of those free services and ad supported isps. I had dial up for a long time and watched the business model go from portal style sandbox like AOL to literal "all internet is free if you keep this ad open. " towards the end before I left for college.
