“SEATTLE — Few golden geese in technology have survived as long as Office has for Microsoft.

The suite of applications that includes Word, Excel and PowerPoint, first released in 1990, generated nearly a third of Microsoft’s revenue during its last fiscal year — about $26 billion of $87 billion in total. By some estimates, the software accounted for an even higher portion of the company’s gross profits.”
