In January 1978, Chicago was hit by the Great Blizzard of 1978

The Great Blizzard of 1978 was a historic blizzard which struck the Ohio Valley and Great Lakes from January 25–27, 1978. The 28.28 inches barometric pressure measurement recorded in Cleveland, Ohio was the lowest non-tropical atmospheric pressure ever recorded in the mainland United States...

, which dumped record amounts of snow throughout the midwest. Among those caught in it were Christensen and Randy Suess, who were members of CACHE, the Chicago Area Computer Hobbyists' Exchange. They had met at that computer club in the mid 1970s and become friends.

Christensen had created a file transfer protocol for sending binary computer file

Computer file

A computer file is a block of arbitrary information, or resource for storing information, which is available to a computer program and is usually based on some kind of durable storage. A file is durable in the sense that it remains available for programs to use after the current program has finished...

A modem is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data...

XMODEM

XMODEM is a simple file transfer protocol developed as a quick hack by Ward Christensen for use in his 1977 MODEM.ASM terminal program. XMODEM became extremely popular in the early bulletin board system market, largely because it was so simple to implement...

. The success of this project encouraged further experiments. Christensen and Suess became enamored of the idea of creating a computerized answering machine and message center, which would allow members to call in with their then-new modems and leave announcements for upcoming meetings.

However, they needed some quiet time to set aside for such a project, and the blizzard gave them that time. Christensen worked on the software and Suess cobbled together an S-100

 computer to put the program on. They had a working version within two weeks, but claimed soon afterwards that it had taken four so that it wouldn't seem like a "rushed" project. Time and tradition have settled that date to be February 16, 1978. Christensen and Suess described their innovation in an article entitled "Hobbyist Computerized Bulletin Board" in the November 1978 issue of Byte Magazine.

Because the Internet was still small and not available to most computer users, users had to dial CBBS directly using a modem. Also because the CBBS hardware and software supported only a single modem for most of its existence, users had to take turns accessing the system, each hanging up when done to let someone else have access. Despite these limitations, the system was seen as very useful, and ran for many years and inspired the creation of many other bulletin board system

A Bulletin Board System, or BBS, is a computer system running software that allows users to connect and log in to the system using a terminal program. Once logged in, a user can perform functions such as uploading and downloading software and data, reading news and bulletins, and exchanging...

Ward & Randy would often watch the users while they were online and comment or go into chat if the subject warranted. Sometime online users wondered if Ward & Randy actually existed.

The program had many forward thinking ideas, now accepted as canon in the creation of message bases or "forums".

As Christensen and Suess went their separate ways, the CBBS name lived on, and survives to an extent as a web-based forum on Suess' website, chinet.com. Christensen's version of CBBS, called "Ward's Board", closed in the early 1990s.
