Step-by-step explanation:
The organization that originated and supports the idea of small businesses operating on a global level is the World Trade Organization (WTO). The WTO was officially established in 1995 but traces its history to the post-Great Depression and World War II era when there was a significant push to create institutions that would integrate the nations of the world. As a predecessor to the WTO, the General Agreement on Tariffs and Trade (GATT) was signed in 1947 by 27 nations to provide a forum for negotiating the reduction of tariffs and other barriers to trade, which later evolved into the WTO with a broader mandate that includes supporting global trade activities, such as small businesses participating in international commerce.
