Sherston Software

Background
Sherston Software (also known as Sherston Publishing Group), was a British software publisher, producing educational games and learning resources. Two teachers, Bill and Lou Bonham, started making games for the BBC Micro in 1983 and set up a limited company in 1991. In 2003, Bill and Lou sold Sherston to a four-man management team, which led to the company being called Sherston Publishing Group. Sherston Software didn't used a proper logo until 1996.
