who is the farther of internet?

the Internet history is begun in far away 1969. The pentagon created one WAN (wide area network) called Arpanet, one military net. Subsequently there was the birth of similar nets in other countries and then the birth of the WWW.

First ISP I ever knew about was prodigy...Don't know who started that..but was it the only one?

The father of the World Wide Web (the most visible face of INTERNET) is Tim Berner-Lee, an englishman. But there were others before him: "The only way the networks of the 1970s could communicate with each other on a wider scale was if someone devised a new language capable of talking to them all. And in 1979 someone did - a key breakthrough that Berners-Lee himself stresses: "If you are looking for fathers of the internet, try Vint Cerf and Bob Khan who defined the 'Internet Protocol' (IP) by which packets are sent on from one computer to another until they reach their destination."" http://www.vnunet.com/webactive/features/2133659/history-internet-origins-web
