Hit Game

WhatsApp is rolling out video calling today to its billion-plus monthly users. That’s basically the entire story — if you’d like to use it, update the app, open a chat, and tap the familiar video camera icon in the top-right corner. The video chat results look like the video chatting you’ve done before on FaceTime, Skype, Facebook Messenger, or Google Duo: two faces, one in a smaller window, with a handful of small features for changing the position of the chat windows or turning the camera around.

That video calls took until November 2016 to arrive on WhatsApp reflects the app’s cautious — some might say glacial — approach to product development. WhatsApp launched in 2009, but group chats didn’t come until two years later, and voice calls didn’t come until four years after that.
