Facebook is launching the first electronic device to bear its brand, a screen and camera-equipped gadget intended to make video calls easier and more intuitive. 

For users, Facebook’s revelation of a data breach that gave attackers access to 50 million accounts raises an important question: What happens next?

Facebook lost about $119 billion of its value on Thursday, marking the biggest one-day loss in U.S. market history.
