ISP
 /I.S.P/

   Common abbreviation for Internet Service Provider, a kind of company
   that barely existed before 1993. ISPs sell Internet access to the mass
   market. While the big nationwide commercial BBSs with Internet access
   (like America Online, CompuServe, GEnie, Netcom, etc.) are technically
   ISPs, the term is usually reserved for local or regional small
   providers (often run by hackers turned entrepreneurs) who resell
   Internet access cheaply without themselves being information providers
   or selling advertising. Compare {NSP}.
