The Full Form of WSIS is World Summit on the Information Society.

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
