Internet service provider

Redirected from Internet Service Provider

Internet Service Provider (ISP), provider of Internet services. Most telecommunications operators are ISPs. Provides services like internet transit[?], domain name registration and hosting, dial-up access, leased line[?] access and colocation.


In the first few years of the Twenty-first Century, many ISPs in the United States have been facing challenges. The stock-market for the telecommunications and IT-related industries went down sharply, and many ISPs were forced to go down, restructure itself, sell itself to another company, or merge with others. The slower-than-expected growth of broadband services, key decisions on broadband open access matters all added harshness to the environment in which they have to survive.

Among the affected are for-profit free ISPs, such as NetZero[?] and Juno Online Services[?], BlueLight[?]; (mostly non-profit) community networks; major players such as AOL, EarthLink[?], MindSpring[?], and AT&T; DSL providers such as Covad[?], NorthPoint Communications[?], and Rhythms NetConnections[?]; and a cable broadband ISP Excite at Home[?].
