In this episode of Tech Teardown, Erin Kennedy discusses the latest developments in the tech sector with Evan Niu, CFA, our tech and telecom bureau chief.

  • Facebook agrees to acquire WhatsApp for a whopping $19 billion. That's an awful lot to pay, but Facebook will be getting an awful lot in return.
  • WhatsApp costs users just $1 per year. That insanely low price point is precisely how its disrupting a $100 billion industry, which is why Facebook wants it in the first place.

  • BlackBerry jumps on news that WhatsApp is selling for $19 billion. Is this move misplaced?
  • LinkedIn makes a big move into content, in part to boost engagement. However, the professional network relies on engagement much less than its peers.
