The telecommunications industries within the sector of information and communication technology is made up of all telecommunications/telephone companies and internet service providers and plays the crucial role in the evolution of mobile communications and the information society.
Traditional telephone calls continue to be the industry's biggest revenue generator, but thanks to advances in network technology, telecom today is less about voice and increasingly about text (messaging, email) and images (e.g. video streaming). High-speed internet access for computer-based data applications such as broadband information services and interactive entertainment is pervasive. Digital subscriber line (DSL) is the main broadband telecom technology. The fastest growth comes from (value-added) services delivered over mobile networks.
The telecom sector continues to be at the epicenter for growth, innovation, and disruption for virtually any industry. Mobile devices and related broadband connectivity continue to be more and more embedded in the fabric of society today and they are key in driving the momentum around some key trends such as video streaming, Internet of Things (IoT), and mobile payments.— Deloitte
Think of telecommunications as the world's biggest machine. Strung together by complex networks, telephones, mobile phones and internet-linked PCs, the global system touches nearly all of us. It allows us to speak, share thoughts and do business with nearly anyone, regardless of where in the world they might be. Telecom operating companies make all this happen.— Investopedia
Of all the customer markets, residential and small business markets are the toughest. With hundreds of players in the market, competitors rely heavily on price; success rests largely on brand name strength and investment in efficient billing systems. The corporate market remains the industry's favorite. Big corporate customers are concerned mostly about the quality and reliability of their telephone calls and data delivery while being less price-sensitive than residential customers. Multinationals, spend heavily on telecom infrastructure and premium services like high-security private networks and videoconferencing. Network connectivity can also be provided to other telecom companies by wholesaling circuits to heavy network users like internet service providers and large corporations.

The telecommunications sector has seen a large increase in the recent years. Whereas in 2015 there were 3.3 billion active mobile broadband subscriptions worldwide, in 2020 there were around 7.7 billion. This increase was due, in part at least, to the deployment of 4G LTE.
During the COVID-19 pandemic, telecommunications supported the fight against the virus and the resilience of economy by various developments, including supporting the developments of heat maps showing the expansion of the virus as well as supporting digital communications for an increased numbers of persons working from home.
