The deal to acquire the videogame developer became the company’s largest, far eclipsing its purchase of LinkedIn (see below) in 2016.

Such was the magnitude of the deal that Microsoft became the third-largest gaming company in the world by revenue – second only to Tencent and Sony.

Nuance Communications

According to the company, Microsoft’s purchase of Nuance Communications would “combine solutions and expertise to deliver new cloud and AI capabilities across healthcare and other industries.”

In so doing, the all-cash transaction would become the third-largest Microsoft acquisition at $19.7 billion.

With Nuance Communications on board, Microsoft was able to accelerate the development of industry-specific cloud solutions.

One such product was Microsoft Cloud for Healthcare, a product introduced in 2020 to provide support for companies in the dynamic and rapidly evolving healthcare industry. 

What Microsoft buys, and why

The pattern: buy a platform with a loyal community and plug it into Microsoft’s cloud and subscriptions. LinkedIn and GitHub fed Productivity and the developer cloud; Activision, ZeniMax and Mojang built a gaming content library for Xbox and Game Pass.

Its biggest AI bet is an investment, not an acquisition: an approximately 25% interest in OpenAI. See Microsoft and OpenAI.

LinkedIn

LinkedIn was acquired in 2016 for $26.2 billion in cash. In a statement, CEO Satya Nadella noted that he expected LinkedIn to be a source of competitive advantage for Microsoft.

More specifically, the platform would complement the company’s existing business-focused software products such as Office and CRM tool Dynamics.

LinkedIn co-founder Reid Hoffman was more philosophical, expressing that the deal was “a re-founding moment” for the company and that the “relationship with Microsoft, and the combination of their cloud and LinkedIn’s network… gives us a chance to change the way the world works.”

ZeniMax Media

Microsoft acquired ZeniMax Media – parent company of video game developer Bethesda Softworks – in 2021 for $7.5 billion. Responsible for titles such as Fallout and Doom, the Bethesda purchase bolstered Microsoft’s first-party Xbox line-up.

Bethesda’s creative team would also be incorporated into the company to make it an industry leader and enable it to honor a commitment to the wider Xbox community.

Affirmed Networks

Affirmed Networks is a company with a core focus on virtualized, cloud-native networking products for telecommunications businesses. Particularly attractive to Microsoft was the company’s 5G and edge computing capabilities with customers such as Orange, Vodafone, Telus, AT&T, and STC. Previously, these customers were inaccessible since they tended to build their own data centers and manage them with proprietary hardware and software.

Mojang

Mojang is a Swedish game developer best known for creating the popular game Minecraft. Mojang spokesperson Owen Hill said that the $2.5 billion Microsoft deal was approved because the co-founders found it increasingly difficult to manage the company on their own.

Moving forward, Microsoft intended to add new content and features to the game without sacrificing its appeal and alienating the game’s loyal core audience.

The OpenAI Deal

In 2016, Microsoft became the leading provider of supercomputing capabilities for OpenAI as the – at the time – research lab embarked on scaling up its large language model — as explored in the intelligence factory race between AI labs — s.

Indeed, the interesting thing about the current AI paradigm is that large language models could be pre-trained with an unsupervised approach, which enabled them to learn patterns from the massive data fed to them.

In addition, those large language models had a very simple object function to generate a text-to-text prediction.

And yet, to perform that simple function at scale, these large language models had to learn patterns from massive amounts of data and billions of parameters, which required a huge amount of computational power.

Here Microsoft enters the picture, thanks to its Azure could provide infrastructure — as explored in the economics of AI compute infrastructure — , which became the go-to supercomputer for the development of OpenAI’s AI models.
