Microsoft’s planned acquisition of professional services network LinkedIn for $26.2 billion could pay off at several levels. For one, it would open potentially new revenue streams to shore up its maturing business portfolio. Two, Microsoft could use LinkedIn to find new ways to market its existing offerings like its Microsoft Office products, Skype and online learning platform Lynda.com. Three, it gives Microsoft a substantial presence in the social networking space that it has coveted for long. LinkedIn has 433 million members, with 60% of them on mobile platforms, according to a Microsoft press note announcing the acquisition.
