World’s Largest Technology Companies

12 Feb, 2021 | Blogs

Walking into 2021, the world’s software companies or the IT industry, in general, witnessed a little glitch with regards to its overall revenue. In August 2020, the International Data Corporation (IDC) — the largest global provider of advisory services and market intelligence for IT companies — estimated the global revenue to be US$4.8 trillion, compared to the previous projection of US$5.2 trillion. Although the IT industry was way ahead compared to any other industry or sector during the COVID-19 crisis, the uncertainties that took place with respect to the postponement of key investments and the severe decline in spending patterns could not be disregarded.

Currently, IDC estimates that the IT industry is taking huge leaps and is on its way to US$5 trillion by the end of 2021. As technology continues to evolve and bring changes to the way people conduct business, it is now important that your business builds strong relationships with global tech brands.

Information Technology continues to alter our everyday lives and how business is conducted. Along with the new technological advancements and innovations, for instance, artificial intelligence (AI), blockchain, cloud computing, large statistics, and IoT (Internet of Things), the global IT market is projected to grow further.

Overview of the Global IT Industry

A recent study by Gartner stated that the overall spending in the global IT industry — including data center systems, telecommunication, business applications, and IT solutions and services — was estimated to be over US$3.7 trillion in 2019, marking a 4.5% increase than the previous year. The global IT spending began to surge in 2018, with persistent growth expected over the next few years.

Currently, the IoT is one of the greatest and fastest-growing segments in the global IT sector. It was estimated to be over US$700 million and is projected to exceed US$2 billion by the end of 2021, growing at a Compound Annual Growth Rate (CAGR) of 30% over the next five years. The top seven robotics companies globally are briefly discussed below, with an emphasis on their revenue and recent developments.
