If you look up the Wikipedia page for WordStar and try to trace who owns the assets now, you find a tall stack of software companies that were acquired by others and eventually it seems to loop.
* WordStar was created by MicroPro International
* They were acquired by SoftKey
* They acquired The Learning Company and took that name
* Then they were acquired by Mattel
* ...which sold the assets to Gores Technology Group
* ...which split into GAME Studios, yet another "The Learning Company", and Broderbund
* ...which was acquired by SoftKey?
Or maybe it was part of one of those Learning Companies that sold its assets to Riverdeep Interactive Learning Limited? I think they're now Houghton Mifflin Harcourt Learning Technology.
