In fact, when the Altair BASIC was first introduced in 1975, the Homebrew Computer Club (a computer hobbyists club) member made unauthorized copies of Altair basic software and distributed them at the club meeting. At that time, MITS Company licensed the software from “Micro-soft” (now Microsoft). Although MITS has been selling thousand computers a month, Micro-Soft wasn’t getting much royalty fees since basic copies have been distributed illegally. This led to the famous open letter “open letter to hobbyists” by Bill Gates which he expressed his frustrations towards the hobbyists. In the letter, he said “As the majority of hobbyists must be aware, most of you steal your software. Hardware must be paid for, but software is something to share. Who cares if the people who worked on it get paid? Is this fair?” But the first implementation of DRM only came about in 1983 by Japanese Engineer Ryoichi Mori and it was implemented in Software Service System (SSS) which is later redefined as Superdistribution. The main focus of SSS was to protect the unauthorized copying by encryption. The SSS would include a
