There were three basic means of distributing software in the 1980s: retailers, mail-order catalogs, and bulletin board systems (BBS). The latter provided the earliest form of “online” distribution, albeit one that was difficult to commercialize. After all, a developer couldn’t ask users to post their credit card number on a BBS.
But you could attach a message to a program uploaded to a BBS that invited people to pay you for software they found valuable. That’s exactly what Andrew Fluegleman did in 1982. Wendy Woods profiled Fluegelman in a January 1985 Computer Chronicles episode that I previously covered. His IBM PC communications program PC-Talk became the first example of “shareware” (although Fluegelman used the term “freeware,” which he trademarked.)
