The Telecommunication Development Advisory Group (TDAG) met for the first time under this new name on 8 and 9 April 1999. Known previously as the Telecommunication Development Advisory Board (TDAB), the group acquired its new name and status at the 1998 Minneapolis Plenipotentiary Conference. Although this change in name was to officially enter into force on 1 January 2000, as will all other amendments to the Union's Minneapolis Convention, TDAG is already in use for practical reasons.
