From a Wall Street Journal story by Aaron Tilley headlined “Apple Is the World’s First $3 Trillion Company”:

Apple on Friday became the world’s first corporation to close with a market value above $3 trillion, a milestone that reflects the lasting impact and resilience of the iPhone, a singular product that continues to transform life and commerce around the world.

Launched from a California garage as a puckish computer company in 1976, Apple is now worth about double the value of longtime rival Google and seven times that of Exxon Mobil, which loomed over markets as the world’s most valuable company for many years.
