The World Summit on the Information Society (WSIS) took place in two stages, one ending in Geneva in 2003 and the other ending in Tunis in 2005. The Geneva Summit produced two outcome documents, the Geneva Declaration of Principles (ITU, 2003a) and the Geneva Plan of Action (ITU, 2003b). The Tunis Summit also produced two outcome documents, the Tunis Commitment (ITU, 2005a) and the Tunis Agenda for the Information Society (ITU, 2005b).
These documents are the key reference points for the follow-up and implementation of the WSIS outcomes.
