MajorMUD

The Major BBS (sometimes MajorBBS or MBBS) was bulletin board software (a bulletin board system server) developed between 1986 and 1999 by Galacticomm. In 1995 it was renamed Worldgroup Server and bundled with a user client interface program named Worldgroup Manager for Microsoft Windows. Originally DOS-based, two of the versions were also available as a Unix-based edition, and the last versions were also available for Windows NT-based servers.

The Major BBS was developed by Tim Stryker and launched in 1986 by Stryker's company, Galacticomm, Inc., as a demonstration of the abilities of the Galacticomm Software Breakthrough Library (or GSBL). The GSBL was a powerful set of assembler routines written for IBM and compatible PCs that allowed up to 32 simultaneous serial port or dialup connections to a single software instance without the need for an external multitasker. It was licensed to developers for varied uses, such as communications systems, bank systems, and real estate systems. Eventually, The Major BBS was enhanced enough that it became a marketable product in its own right. By late 1987, Galacticomm was licensing more copies of The Major BBS than the GSBL by itself. The GSBL continued to be enhanced, expanding to 64 users by 1988, then 256 by 1992, with The Major BBS's line capacity expanding as a result.

Because it was one of the few multi-line bulletin board systems, MBBS software was known for fostering online communities and an interactive online experience where users were able to interact with each other via Teleconference (chat rooms) and multiplayer games. This flexibility spawned a small industry of Independent Software Vendors (ISV) who began developing MBBS add-ons, which ranged from shopping malls (what would now be called shopping cart software) to online role playing games.
