Short for Internet Service Provider. This is the company you purchase your internet connection from. Usually associated with a monthly fee, the service provider will in exchange offer a software package and connection associated with a username, password, method of connection. In the US, most DSL and Cable providers offer access to usenet alongside the package. This usenet access is often times substandard, with very low retention rates (how old of a post you would be able to read), as well as unstable connection rates, and limited connection channels. ISPs also clearly state in the TOS that activity of the users on the network would be shared upon the discretion of the ISP to third parties. Newsdemon strongly advises to use another source to connect to any newsgroup using a third party company such as Newsdemon rather than using an ISP.
