The world’s oldest international organization — the International Telecommunication Union (ITU) — will mark the anniversary of its founding on May 17. The ITU was established on that day in 1865.

The theme of the 2016 World Telecommunication and Information Society Day will be “Information and Communication Technology (ICT) entrepreneurship for social impact.”

The ITU asserts that ICT entrepreneurs and startups, and small to medium size enterprises “have a particularly relevant role in ensuring economic growth in a sustainable and inclusive manner.” In conjunction with World Telecommunication and Information Society Day, radio amateurs in Australia will be permitted to use the prefix “AX” on May 17.
