While the survey found that most traditional ISPs reported slow growth during the usually booming post-holiday online season, Microsoft Network (MSN) saw a 25-percent increase to 5,000,000 in its number of subscribers. Verizon, with a 33-percent growth rate to 720,000 subscribers, was the only major DSL provider to report a significant number of new users, and it surpassed SBC as the dominant DSL provider, as SBC reported a 25-percent decline in the number of subscribers, down to 600,000. Rounding out the top five are Covad, Qwest and EarthLink, according to TR's Online Census. Road Runner, the number-two player in the [cable] market after @home, attributes some of its 63-percent growth rate during the first quarter to the volatility in the DSL market.

There are now [Fall 1996] 3,068 Internet service providers (ISPs) listed in North America. That's a doubling in the past seven months. The average ISP has annual revenues of $637,572 and 13 paid employees, and it provides 199 dial-up telephone ports to 1,844 Internet users.
The ratio of phone lines to customers is recommended to be about 5:1 for small providers, 6:1 for more than 100 modems and 10:1 for more than 300 modems. It is claimed that a T1 can support about 200 phone lines, i.e., an oversubscription factor of about 3.8. It is claimed that you can run 10 or 20 simultaneous users on a 56 kb/s line, but that may have been in 1994.
