The first public dial-up BBS was developed by Ward Christensen and Randy Suess.
Back in the Jurassic age of computing, when Apple IIs ruled the earth, a couple of Chicagoans named Ward Christensen and Randy Suess wanted to make it possible for their personal computers to exchange information.
Ward Christensen invented the first public BBS in the late 1970s, and another ( named " The WELL " ) in the late 80's and early'90s arose as a popular online community.
The first breakthrough came in the late 1970s when Ward Christensen, an engineer with International Business Machines Corp . and an early personal computer enthusiast, invented an error-correction technology and released it to the public domain.
However, Ward Christensen refused to do this, as it was precisely the " lack " of these features, and the associated coding needed to support them, that led to XMODEM's widespread use.
