It was established on 25 July 1925 by a decree Presidium of the Supreme Soviet of the Soviet Union. Tass was created from the Russian Telegraph Agency (ROSTA), the first state news agency in Soviet Russia. The agency was frequently infiltrated by the Soviet intelligence and security agencies, the NKVD and GRU. Many of its employees also voluntarily served as information sources of intelligence to the NKVD (later, the KGB).
In 1992, following the dissolution of the Soviet Union, it was inherited by the Information Telegraph Agency of Russia (ITAR-TASS).
