GATT formed 1949 was replaced by WTO in 1995

The General Agreement on Tariffs and Trade (typically abbreviated GATT) was negotiated during the UN Conference on Trade and Employment and was the outcome of the failure of negotiating governments to create the International Trade Organization (ITO). GATT was formed in 1949 and lasted until 1993, when it was replaced by the World Trade Organization in 1995. The original GATT text (GATT 1947) is still in effect under the WTO framework, subject to the modifications of GATT 1994
