Almost a decade after acquiring it, Mark Zuckerberg taps the strengths of WhatsApp

When Facebook bought WhatsApp for $19 billion nearly a decade ago, Mark Zuckerberg made a promise: The Facebook chief said he wouldn’t meddle often with the messaging app so as not to mess with a good thing.

Zuckerberg stuck to that philosophy as WhatsApp amassed more than 2 billion users globally — until 2019, when he began tapping the app’s growth and business potential.
