The name Listserv was first used in 1984 to refer to a mailing list application that operated over the BITNET network: BITNIC LISTSERV. In 1986, a completely different application was created and named Revised Listserv. Revised Listserv was the first automated mailing list application, and by 1987, even users of BITNIC LISTSERV had upgraded to Revised Listserv due to its automated mailing list management features.
