Koum: When Apple introduced push notifications, we introduced a feature where if you change your status, it could go out to all your contacts — like a broadcast. We noticed that some people were actually using it as a communication method.
People would write in and say — look, you kind of have this way for me to communicate with my friends using push notifications. Meanwhile I'm paying 25 euro cents for a text message. Why don't you just pipe it together? You're 90% there. You already know who in the address book uses WhatsApp. You're already using push notifications.
