The World Summit on the Information Society (WSIS) was a two-phase United Nations-sponsored summit on information, communication and, in broad terms, the information society that took place in 2003 in Geneva and in 2005 in Tunis. One of its chief aims was to bridge the global digital divide separating rich countries from poor countries by spreading access to the Internet in the developing world. The conferences established 17 May as World Information Society Day.
The WSIS+10 Process marked the ten-year milestone since the 2005 Summit. In 2015, the stocktaking process culminated with a High-Level meeting of the UN General Assembly on 15–16 December in New York.
In the last decades of the 20th century the new Information and Communication Technology (ICT) was implemented, especially in the developed countries. Using ICT changed the modern society in many ways which is known as digital revolution, and therefore new opportunities and threats had been raised. The world's leaders were hopeful to solve many problems using ICT. At the same time they were concerned with digital divide at an international level as well as at a national one which could lead to shaping new classes of those who have access to ICT and those who have not.
In such circumstance, recognizing that these challenges and opportunities require global discussion on the highest level, the International Telecommunication Union (ITU), following a proposal by the government of Tunisia during ITU Plenipotentiary Conference in Minneapolis in 1998, approved Resolution 73 to hold a World Summit on the Information Society and put forward it to the United Nations. In 2001, the ITU Council decided to hold the Summit in two phases, the first from 10 to 12 December 2003, in Geneva, and the second from 16 to 18 November 2005 in Tunis.
