In the mid-1980s, both CCITT (now ITU-T) and ISO had standardization groups for image coding: CCITT Study Group (SG) VIII (Telematic
Services) and ISO TC97 SC2 WG8 (Coding of Audio and Picture Information). They were historically targeted on image communication. In 1986, it was decided to create the
77:(JPEG SG) and the Joint Bi-level Image experts Group (JBIG SG). After completing the 2019 edition of the JBIG2 standard, the JBIG subgroup was closed and its maintenance responsibilities were assigned to the general JPEG group.
