Unstoppable Microsoft was disrupted mostly by the rise of mobile phones. As long as PCs were the main device, they were the unstoppable monopoly (with Apple capturing an extremely lucrative but rather small 10% or so Market segment and nothing else even registering). They woke up one day and realized people now consume media through their phone; but they were already unseated at that point (their phone ecosystem, due to tie ins into the Windows system, could not compete in the brand new iOS/android/blackberry world of the time; and shortly after, neither could blackberry) I believe zuckerberg is branching into anything he thinks might at some point be "the next thing", including VR, because of how Microsoft missed the train. It seems Microsoft believed they can always throw enough money while playing the long game and get a dominant position (as happened with internet/ie, Xbox, etc) - but it seems this strategy has failed miserably with mobile, tablets and may eventually cost them a lot more dominance.
