Exhibition; the what & why?

I read too many articles, browsed through too many links to try to find an exact definition which can perfectly define the word “exhibition”, however; there are neither too many stories to follow nor too many perspective of looking at this. Nevertheless, all different definitions had finally come to a point ultimately and the magic word to explain this is “marketing tool”. 

Unlike any other marketing tools or channels, this is the best of all. Reason is simple, exhibition alone can achieve so many marketing objectives such as Mass reach of advertising, Targeting of direct mail, Persuasive power of face-to-face selling, Networking benefits of Internet, brand reputation building of PR & branding Creating a unique environment and atmosphere. 

For that I would say exhibition is no longer a single medium in this new era but a perfect mixture and best form of investment for corporate which is why Google Inc. has more than 5000 exhibitions annually, which makes at least 14 exhibitions every single day of the year. Do you know MNCs from overseas invest 60-70% of total corporate capital into exhibitions for marketing purpose where as Malaysia companies only invest less than 10% of total corporate capital into exhibitions for the same purpose?
