Information and communication technology, or ICT, is the combined field of computing, networking, telecommunications, software, data, devices, media, and digital services. The phrase is broader than "IT" because it emphasizes communication networks as well as information systems. It includes broadband, mobile networks, cloud platforms, collaboration tools, data centers, cybersecurity, digital identity, enterprise applications, AI systems, and the skills and policies needed to use them well.
In 2003, ICT was often discussed as a way for companies to become "networked" after the dot-com crash. In 2026, that framing has become ordinary reality. Most organizations now depend on ICT for customer experience, supply chains, remote work, payments, analytics, compliance, operations, software delivery, and resilience. The challenge is less whether technology matters and more whether leaders can govern it, secure it, and turn it into useful capability.
What ICT Includes
- Connectivity: fixed broadband, fiber, mobile networks, Wi-Fi, satellite, private wireless, and enterprise WAN services.
- Computing platforms: data centers, public cloud, private cloud, edge computing, virtual machines, containers, and serverless services.
- Applications: ERP, CRM, collaboration, messaging, document management, workflow, analytics, e-commerce, and industry-specific systems.
- Data and AI: databases, data lakes, governance, machine learning, generative AI, automation, decision support, and model risk management.
- Cybersecurity: identity, access control, endpoint security, encryption, monitoring, incident response, resilience, and supply-chain security.
- Digital inclusion: affordability, access, accessibility, skills, language, local content, and meaningful connectivity.
- Governance: strategy, architecture, standards, procurement, vendor risk, privacy, ethics, and measurement.
ICT and Digital Transformation
Digital transformation is not simply replacing paper with software or moving servers to the cloud. It is changing how an organization creates value, coordinates work, serves customers, learns from data, and adapts to change. ICT provides the tools, but the transformation depends on operating model, skills, process redesign, incentives, and leadership.
This was the strongest part of the 2003 argument on the original page: the industry should stop looking for one "killer application" and focus on a "killer approach." That idea has aged well. The important breakthroughs usually come from connecting systems, people, data, and processes so the organization can act faster and more intelligently.
The Digital Divide
The digital divide is still a central ICT issue, but the definition has become richer. It is not only whether a person or organization can connect to the internet. It is whether the connection is affordable, reliable, fast enough, safe enough, accessible, and paired with the skills and devices needed for meaningful use.
ITU's ICT Development Index 2024 focuses on progress toward universal and meaningful connectivity, defined as the ability for everyone to go online under optimal conditions, affordably, anywhere and anytime they need. That framing matters because a slow, shared, expensive, or unreliable connection may technically count as access while still limiting education, work, health care, public services, and entrepreneurship.
ICT in 2026
Several forces now define ICT strategy. Cloud computing made infrastructure programmable and global. Mobile broadband made digital services continuous. Cybersecurity became a board-level risk. AI turned data and compute into strategic assets. Digital sovereignty and privacy laws made data location and governance more important. Sustainability concerns pushed organizations to measure energy use, e-waste, and supply-chain impact.
The OECD Digital Economy Outlook 2024 highlights how ICT and internet technologies shape public policy, innovation, and inclusive growth. It also notes strong ICT-sector growth in OECD countries in 2023 and the value of measuring digitalization with better and faster indicators. In other words, ICT is no longer background infrastructure. It is a measurable part of economic performance.
The 2003 BT Speech
During his keynote speech at ITU Telecom World 2003 in Geneva, Andy Green, then BT executive board member and chief executive officer of BT Global Services, focused on hidden opportunities for business leaders in the digital age. He described changes required in corporate thinking to take advantage of the digital networked economy and questioned whether the ICT industry was mature enough to meet the challenge.
Green rejected the ICT industry's fascination with a "killer application," favoring instead a "killer approach" built around fully networked companies. He explored the concept of a "true digital divide," arguing that European organizations in particular were failing to link ICT to corporate strategy and adapt their business models for the digital networked economy. He warned that this would cause Europe to fall behind hungrier economies in the global productivity race.
Green said: "The technology is in place and ready, but businesses are not. There is some post-dotcom lethargy in boardrooms, and too many leaders seem to be taking the attitude that ICT is no longer important for their business."
He added: "We are in the digital network age, the applications are there. We need to bring them to our people, our customers and our suppliers. Vast power is out there but only a fraction is being used. We are on the verge of a massive leap forward in productivity that will be driven by networking it all together. Successful companies will emerge from the pack by harnessing the existing power within their businesses, using it efficiently, and distributing it widely, allowing collaboration inside and outside the organization. Instead of focusing all their efforts on cost reduction, CIOs and CEOs have a new opportunity to develop business strategies that use IT to change the way an organization works, to gain competitive advantage in the digital networked economy. This is what BT stands for."
Challenging the ITU audience, Green also said: "In order to help businesses achieve that transformation, providers of networks, software, hardware and services are going to have to work more closely together to create open and flexible environments that allow customers to innovate. BT is at the forefront of that effort, to create open wholesale markets, develop standards for interoperability and global commercial models. The question now is: do the converging IT and Communications industries really understand what needs to be done and do they have the maturity to accept and take on the challenge. Is the industry up to delivering on the promise of the digital networked economy?"
What Changed Since 2003
The industry did move toward the networked model Green described, but not in the exact shape imagined in 2003. Broadband, smartphones, social platforms, SaaS, cloud hyperscalers, app stores, APIs, video meetings, data analytics, and AI transformed business more than any single telecom-era "killer app." The most successful organizations treated ICT as a way to redesign work, not merely a way to reduce telecom or IT costs.
At the same time, the risks became larger. Ransomware, outages, platform concentration, misinformation, surveillance, privacy breaches, AI misuse, and supply-chain dependence all show that ICT strategy cannot be separated from governance. The boardroom question is no longer "does ICT matter?" It is "can we use ICT responsibly, securely, and productively without becoming fragile?"
ICT Strategy Checklist
- Connect ICT investments to business, public-service, or mission outcomes rather than treating them as standalone technology upgrades.
- Measure access, adoption, skills, reliability, security, cost, and productivity impact, not only equipment purchased or systems deployed.
- Design around interoperability and data portability where possible to reduce lock-in and improve resilience.
- Make cybersecurity and privacy part of architecture from the beginning, not an audit step at the end.
- Invest in digital skills for users, managers, technical staff, and executives.
- Govern AI and automation with clear accountability, data quality controls, human oversight, and risk management.
- Plan for sustainability: energy use, cooling, device lifecycle, e-waste, procurement, and cloud/data-center efficiency.
- Keep inclusion visible. A digital system that excludes users because of affordability, disability, language, geography, or skill level has not fully solved the problem.
ICT is the connective tissue of the modern economy. The lesson from 2003 still applies: value comes less from chasing one application and more from building organizations, markets, and public systems that can use information and communication technologies coherently.
