Softdisk was a publisher of "disk magazines" -- magazines distributed on disk, with programs, interviews, advertisements, etc. They were very popular from the 1980s until the mid 1990s, when the World Wide Web explosion changed the computer into a true consumer device. The programs were sometimes helpful utilities, but were mostly games you could play. Softdisk acted as a game publisher, and paid authors for their work.
A history of the company is still available on the web.
