Special interest group

A special interest group (SIG) is a community within a larger organization with a shared interest in advancing a specific area of knowledge, learning or technology where members cooperate to effect or to produce solutions within their particular field, and may communicate, meet, and organize conferences. The term was used in 1961 by the Association for Computing Machinery (ACM), an academic and professional computer society.^[1] SIG was later popularized on CompuServe, an early online service provider, where SIGs were a section of the service devoted to particular interests.^[2][3][4]
