A famous event in the history of software copyright policy was an open letter written by Bill Gates of Microsoft, dated February 3, 1976, in which he argued that the quality of available software would increase if "software piracy" were less prevalent. However, until the early 1990s, software copyright infringement was not yet considered a serious problem by most people. In 1992, the Software Publishers Association began to battle against this phenomenon, with its promotional video "Don't Copy That Floppy". It and the Business Software Alliance have remained the most active anti-infringement organizations worldwide, although to compensate for extensive growth in recent years, they have gained the assistance of the Recording Industry Association of America (RIAA), the Motion Picture Association of America (MPAA), as well as American Society of Composers, Authors, and Publishers (ASCAP) and Broadcast Music Incorporated (BMI).
