In today's landscape, there is just no way you can underestimate the power of the audience. Today, if you lose audience attention, they are going to turn to their phones. And on their phones, they will talk about your event with all of their followers. It's for this reason that you have to constantly be thinking about what you're doing to engage the audience. Gone are the days when you could put on a bad event and it would remain with the attendees. Today, those attendees will tweet, snap, facebook. It is on you, the event planner, to make sure you're creating an event that the audience will remember.
