What is the main purpose behind hosting PR events?

In my view, PR events are always organized with a specific motive which could be anything i.e. To introduce a new board member or senior official, to unofficially launch a new product or service, to make people remember that company/ organization is very well connected with its clients (Old, existing & new) or any matter of importance and is in the great interest of the company.  

Also, PR events is an opportunity to uplift/ polish  the image of the organization. A successful PR event not only re-establishes a brand in its segment, but also give an imputes to further educate and inform people/clients/customers what companies vision is and why a platform has been provided to the employees and customers to interact and share their views with each other. 

Last but not the least, PR events have different definition in different industries(Manufacturing/ Media/ Hospitality etc.). For instance a conference or seminar could also be called as a PR event if it organized by an Industry body, however if organized by a professional firm then it is projected and planned in an entirely different manner though the purpose could be same.

my point of view on pr event is little bit different. i always want feedback, so eye contact is batter way. so purpose is simple in event feedback and impact or your event.

Persuasion is an effective tool of public relations and is always welcome. In some cases you may find that the other party feels irritated when you constantly tried to persuade him, but in all cases, persuasion is always rewarding and brings desired results if you have the patience.
