Bitnet

BITNET was started in 1981 with a link between Yale University and the City University of New York. While BITNET users can send and receive Internet mail, it is not part of the Internet itself (although many BITNET sites are on both networks). Internet users are probably most familiar with BITNET through LISTSERV, the mailing list server that originated in BITNET and is now used widely on the Internet.
