It feels like the world is getting faster. It’s become a cliche to refer to the “exponential progress” of technology, but between Moore’s Law and similar (if less easily measured) trends in software development, exponential progress is a reality. This reality is reflected in the history of tech leaders as well. IBM dominated the computer industry from the release of System/360 in 1964 until the commodization of PC hardware thanks to Microsoft, which consolidated its position with the release of Windows 3.1 in 1992. Microsoft was the industry king and Wall Street darling until it became clear that the web was the new desktop, catapulting Google (almost by default) to the top of the industry circa 2004. Sometime in the next decade – the timeline is unavoidably fuzzy, because the transition isn’t over – it began to feel like Facebook has a greater claim to the title of sector leader.
