"The term Listserv (written by the registered trademark licensee, L-Soft International, Inc., as LISTSERV) has been used to refer to electronic mailing list software applications in general, but is more properly applied to a few early instances of such software, which allows a sender to send one email to the list, and then transparently sends it on to the addresses of the subscribers to the list.The original Listserv software, the Bitnic Listserv (also known as BITNIC LISTSERV) (1984\u20131986), allowed mailing lists to be implemented on IBM VM mainframes and was developed by Ira Fuchs, Daniel Oberst, and Ricky Hernandez in 1984.
