First, SGE was founded in December 31, 1972 as the OIRT's third television channel called, The Third Color Channel of the OIRT or OIRT 3, and the first own era. Second, OIRT ceased to be at the end of 1974 because it was decided that the OIRT would be broken up into smaller entities, including two separate organisations for each of the TV channels in 1974, and The Third Color Channel of the OIRT or OIRT 3 was renamed to SGE.
