Jim Knopf


About “Jim Knopf”:

Jim Knopf, nicknamed Jim Button, was considered by many to be one of the "fathers" of shareware. As an IBM employee, he wrote a program to help with a local church congregation. When demand for his program consumed too much of his time, he quit IBM and created Buttonware. He released his first program, PC-File, in late 1982 as "user supported software".
