Enterprise Systems Media

Enterprise Systems Media, Inc. (ESM) was originally founded by Bob Thomas in 1981 and has been publishing IT magazines since that time. Originally named Thomas Publications, Inc., ESM has operated under several names, the most recent being MainframeZone, Inc. Always a publisher of vertical IT magazines, ESM’s first publication was Unisphere, a magazine targeted to users of UNIVAC computer systems. Because of the pre-eminence of IBM at the time, 4300 Quarterly was launched in 1986. Eventually that magazine became Mainframe Journal and following the announcement of IBM’s System/390 family in 1990, it was renamed to Enterprise Systems Journal. Source
