Majong's founders, Notch, Carl, and Jakob, are leaving the company. In a statement on the company blog, the Minecraft developer said: "We don’t know what they’re planning. It won’t be Minecraft-related but it will probably be cool."
Since the start of 2014, Microsoft has acquired six companies, including Mojang. Of these six, four were headquartered outside the U.S. (Microsoft also is believed to have bought wearable computing intellectual property from San Francisco-based The Osterhout Design Group, though it didn't buy the entire company.)
Microsoft is interested in using its billions of overseas cash to acquire companies and technologies so as to avoid paying hefty U.S. taxes the company would accrue by spending that money on U.S. companies.
Here's a list of the companies Microsoft bought so far this year:
There have been rumors that Microsoft plans to make another acquisition of a non-U.S.-based company before this year is out. The Wall Street Journal reported earlier this year that Microsoft was working to purchase Israeli cybersecurity startup Aorato. Aorato is focused on improving the security IT infrastructure, including that of Microsoft's Active Directory technology.
