Its name changed to .\" American National Standards Committee X3 (ANSC-X3) and now it is known .\" as Accredited Standards Committee X3 (ASC X3). It is accredited by ANSI .\" and administered by ITI. The subcommittee X3.2 worked on coded .\" character sets; the task group working on ASCII appears to have been .\" designated X3.2.4. In 1966, ASA became the United States of America .\" Standards Institute (USASI) and published ASCII in 1968.
