Microsoft on June 19 announced the purchase and audio-visual education platform Flipgrid, but did not disclose the amount of detail, if it is not surprising that the single news, but in fact, Microsoft spent 7.5 billion of dollars to buy the open source project platform GitHub, even after the 2018 years of the end of the E3 video game exhibition, Take a breath to buy 4 game studios, including Ninja theory, Playground Games, undead Labs, Compulsion Games, big and small purchase and immediately let outside Curiosity Microsoft Daxing Purchase and the behind-the-scenes reasons. The Zack website says Microsoft may have three reasons to buy. First, Microsoft continues to reduce the importance of PC business. The PC industry has entered a mature market, a wake-up call for Microsoft, the PC software kingdom, which has been tweaking its PC business, most notably by allowing users to upgrade Windows 10 for free and the focus of the PC business on other software, such as Office 365.

Second, mergers and acquisitions are a quick way to shorten the gap with rivals, especially when Microsoft touches new business, and Flipgrid is a clear example.
