The Google Publisher Program allowed independent authors and small presses to sell ebooks in the Google Play bookstore. When the program was active it become a cesspool of piracy. Fake authors would sell ebooks they never wrote and publishing companies would rename all of the main characters in Harry Potter or 50 Shades of Grey and would peddle them off as their own original works. In 2015 Google closed their publisher program and for the next four years the only way authors and publishers could get their digital content on the platform is through aggregators. Today, Google has just reopened their Play Books publisher program with a few new caveats.
