ITU Telecom World started out life in Geneva in 1971, with “a message to the 21st century”. In 1971 ICT was all about telecoms; voice over a fixed infrastructure, run by national operators out of government departments. Innovations included switching and transmission equipment, videophones, audio-visual equipment and television studios, communications or research satellites.

Engineering had advanced rapidly in the run up to Telecom in 1979. Innovations included the collaborative British exhibit “System X”, which made its debut as an electronic telephone switching system. Cutting edge audio-visual equipment of the time helped simultaneously deliver Forum discussions, interviews and showcases in the Exhibition to external audiences.

National pavilions from across the world joined TELECOM in 1983, which also saw the first appearance of China and AT&T at a TELECOM event. The Forum was in three main parts, with three different themes, covering the managerial, technical and legal aspects of telecommunications. A key discussion area was ISDN networks, at that time under consideration as the worldwide information highway.

Exhibitors at TELECOM ’91 showcased how information could be collected, managed, shared, processed, transmitted and received, irrespective of its form (text, voice, pictures of data) technology or message destination. The Forum explored key issues from accessibility to interconnection and interoperation and the implications of the global shift to deregulation and advent of competition.

Highly influential figures from across government and the industry, including Nelson Mandela, launched Telecom 1995. It was an ICT extravaganza, reflecting new trends such as convergence, with the rapid growth of computer networks, the internet and inclusion of software companies in the tech ecosystem all on display on the showfloor and explored in the Forum.

Telecom 1999 highlighted one of the most major trends in this era; the convergence of the internet with mobile technology. Innovations on show included a prototype smartphone, WAP (wireless application protocol) applications, the first steps towards a mobile Internet. The Forum encompassed 5 summits and combined sessions, focussed on areas such as Connected society, policy & regulatory or disaster mitigation and relief


First third-generation (3G) system bringing faster services and internet access deployed in Japan


Innovative wireless Internet applications and mobile devices with in-built digital and video cameras dominated showcases at ITU Telecom World 2003. Other key themes reflected at the event included extending the reach of telecommunications into developing markets, with calls for the industry to look to the future and provide affordable services backed by regulation to facilitate growth. The Forum tackled issues from broadband and mobility, to new business models and new sources of revenue.


Under the theme “Living the Digital World”, ITU Telecom World 2006 in Hong Kong explored the trends, technologies and policies that are driving a digital world. Innovations on show included broadband-in-action at home and in the workplace, new, converged product offerings and IP-enabled services such as TV and Video. Extending the information society and promoting access to ICTs was a major theme. In the Forum, policies were explored and best practice cases highlighted.

Forging top-level strategies aimed at harnessing the power of technology to enhance our global wellbeing were the focus of ITU Telecom World 2009 in Geneva. Key topics explored on the Show Floor and at the forum included mobile broadband growth, m-payments, cybersecurity, extending access to ICTs and the challenges of regulation in a fast-changing environment.


By ITU Telecom World 2011, which took place in Geneva, the focus had moved towards debates and forums, with a Forum programme featuring new streams such as the Digital Cities programme and an in-depth Technical Symposium for CTOs and Engineers. The show floor highlighted opportunities in emerging markets across Africa, Asia, the Middle East and Eastern Europe.



ITU Telecom World 2013 headed to Bangkok to explore the seismic change taking place in the ICT industry and its far-reaching impact. It featured pavilions from across the globe including the then worlds youngest country, South Sudan. Showcases explored new opportunities in voice and messaging, IPv6, TD-LTE, to name just some, and Forum discussions tackled areas from IoT, the future of broadband or OTT tech to 3D printing or the transformative impact of the Internet in Africa.



ITU Telecom World 2015, in Budapest, was the first Telecom event to specifically reach out to SMEs from across the globe. They joined alongside major corporates and national pavilions, also taking part in the first edition of the ITU Telecom World Awards. Global innovation was the focus of the event, with showcases exploring 5G to e-governance, satellite and more. Forum discussions provided important dialogue between government and start-ups, and between established industry players and SMEs.






5G, the fifth generation technology standard for cellular networks, starts to be rolled out – starting with South Korea in April 2019


ITU Telecom World went virtual – in response to the ongoing global COVID-19 pandemic – and took on a new name to reflect the range of technologies and stakeholders in the industry ecosystem: ITU Digital World. Held online with co-hosts Viet Nam, ITU Virtual Digital World 2020 included Ministerial Roundtable and Forum debates on the impact of the pandemic, 5G and broadband networks, as well as a virtual exhibition.
