For the first time ever, according to Bloomberg data, the five highest-value companies in the world are all in the tech industry. The players are the ones you’d expect—Apple, Google, Microsoft msft and so on—but it marks a milestone that should be encouraging to investors and job seekers alike.

Apple aapl leads, with a $571B market capitalization, followed by Alphabet (Google) goog at $540B and Microsoft at $441B. Amazon amzn followed at $364B, and Facebook rounded out the top five at $357B.

Amazon and Facebook fb are the big news here. The companies knocked oil giant ExxonMobil xom out of the top five, where it’s held a spot since 1980—even during the early-2000s dot-com bubble. Literally: This has never happened before.
