People want everything "here and now" since the importance of time is much more than it use to be a decade ago. In North America, almost every other person we see has a mobile device on them - or two, or three, maybe even more. These devices allow for quick access to information, especially through platforms such as Facebook. There are many news outlets and businesses that promote their stories via the news feeds on such applications.
