Industry research firm Gartner has revealed the 100 biggest tech companies in the world, as measured by their 2016 revenue from information technology and components.
Google's revenue for 2016 came in at $90 billion, pushing it ahead of Microsoft which fell to fourth place with it's $86 billion in revenue.
Gartner has unveiled its top 100 vendors in IT, with iPhone giant Apple taking the top spot with more than $218 billion in IT revenue.
"The needs of IT buyers are shifting". Garnter is pitching the list as a way for tech business leaders to benchmark competitive performance against a shift from the Nexus of Forces to digital business as the driver of IT purchasing.
"The Nexus of Forces has been the focus of attention for many years, however, the impact of digital business is giving rise to new categories". "CEOs are focused on growth and are more focused on realising business outcomes from their IT spend", Gartner analyst and vice president, John-David Lovelock, mentioned.
Microsoft was a large and influential company when the Nexus of Forces began, having grown to market leadership during the web and e-business phase, and has managed to pivot to remain relevant.
IBM gained its size and market dominance in the very earliest IT markets when servers, storage and consulting services dominated.
Gartner says that as enterprises increasingly digitise their products and services, digital giants Google, Apple, Facebook, Amazon, Baidu, Alibaba and Tencent can become involved in, "or even take over the digital experience".
He also mentioned that the focus of the digital giants has mainly been in the consumer, citizen and employee world, and said that because the digital giants have not yet been as focused on B2B, there is opportunity for other companies to take the lead.
"Digital giants effectively become gatekeepers for any business that delivers digital content and services to consumers", Lovelock said in a statement.
While the current digital giants are heavily focused on consumer activity, Gartner analysed that there is a gap in the market for selling digital services for business-to-business activities, citing Amazon's effort to grow its Amazon Web Services cloud arm. "Apple's iOS devices are dominant within enterprise mobility, and Google's presence beyond search into browsers, cloud office and more is growing", he added.
