About World Telecommunication and Information Society Day

World Telecommunication and Information Society Day is observed on 17 May. It highlights the role of telecommunications, the Internet and other information and communication technologies in societies and economies, including efforts to bridge digital divides.

The observance combines the history of World Telecommunication Day with the later information-society observance, so the guide keeps that institutional evolution visible instead of treating the current name as timeless.

Why World Telecommunication and Information Society Day matters

Connectivity can affect access to information, public services, education, commerce and emergency communication. At the same time, access, affordability, accessibility, safety and meaningful use are different issues and should not be collapsed into one statistic.

Because technology and connectivity indicators change rapidly, evergreen institutional history should remain separate from current adoption figures, rankings or annual themes.

History of World Telecommunication and Information Society Day

World Telecommunication Day has been celebrated on 17 May since 1969. ITU explains that 17 May marks its founding in 1865, when the first International Telegraph Convention was signed in Paris.

After the World Summit on the Information Society called for a World Information Society Day, the UN General Assembly acted in 2006; later that year the ITU Plenipotentiary Conference combined the observances as World Telecommunication and Information Society Day.

The first annual observance under the combined World Telecommunication and Information Society Day name followed in 2007 after the 2006 ITU merger decision.
