 Since the invention of the first electronic communications systems in the 1830s, the world has been changing. Information and communication technologies, ICTs, are evolving at an ever faster pace, reshaping the world around us. In 1998, ITU, the United Nations body for ICTs, proposed a new kind of global dialogue on the impact of technology. Called the World Summit on the Information Society, this meeting was the first UN summit-level discussion open to all. We wanted to hear from everyone, everywhere, because if technology is really going to change our lives for the better, no one can be left out of the conversation. Together, the world agreed on a blueprint to guide equitable access and ongoing development of ICTs. In the decades since, these principles have shaped global efforts to harness technology to drive development and foster innovation. And every year, the WESIS Forum gives the global community the chance to take stock of achievements and remaining gaps. In 2014, WESIS Plus 10 created a fresh set of priorities for an ICT-powered sustainable future. WESIS remains the most open, inclusive and accessible global platform on the way technology is changing and enriching all our lives. ICTs are key to achieving truly global sustainable development. Let's make it happen.
