One of the dogmas of the entire modern communication, starting from the fact that today the users are much more satiated than in the past and in the net you can quickly confirm or deny what the brand say, is to demonstrate what is claimed to know how to do, whether it is a simple skill or even a worldwide asset. To do it you do not design the concept of the event on communication but on the contrary communication must serve and document what has materially been demonstrated in the event.
