The United Nations' Economic and Social Council concerns itself with the world’s economic, social and environmental challenges. It was established in 1946 and issues policy recommendations. It also has broad responsibility for around 70 percent of the UN's finances.
The Council holds regular meetings throughout the year with business, academica and NGOs. Most important is it annual, month-long session in July each year, alternating location between New York and Geneva. In terms of Internet policy and governance, ECOSOC oversees the Commission on Science and Technology for Development (CSTD); the body where most topics are dealt with formally within the United Nations.
ECOSOC has been fighting somewhat of a turf war with another arm of the UN, UNCTAD (UN Conference on Trade and Development), over Internet governance issues. UNCTAD is connected to the CSTD and closely involved with the Internet Governance Forum (IGF). ECOSOC website can be found at: http://www.un.org/en/ecosoc/
