> Um, we had phones before mobile phones.

True, but back in the day one had to pay for every call, sometimes at per-minute rates: always so for long distance, and in some areas even for local calls. Quite a contrast to today's unlimited-minutes cellular plans (which likely get used little enough that the providers have no trouble offering them).

A key factor in the development of dialup BBS systems in the US was that local calls were usually at least flat-rate, with unlimited service available here and there.

Bringing it back to the topic at hand, back then I recall a number of social events revolving around local BBSes in Champaign-Urbana, and Fidonet's Net 115 in the Chicago area. All that sort of thing vaporized pretty quickly once the internet opened up.
