While in essence I can't dispute this, I believe the same could be said about advertising or any other marketing tool or discipline.
PR's strength within live events lies in brand amplification - making sure they reach an audience that is greater than simply those engaged in the event. While it is certainly more effective at this than advertising, it is still facing the same problems of proliferation and overpopulation of media.
There is always going to be room for specialist experiential marketing agencies such as ourselves. However, what is certainly true is that the lines between experiential and PR are becoming less defined.
