what is the world expo

A World Expo, also known as a universal exhibition or an expo, is a large international exhibition designed to showcase the achievements of nations. These exhibitions vary in character and are held in different parts of the world at a specific time. There are two types of international exhibitions: World Expos and Specialized Expos. World Expos, previously known as universal expositions, are the biggest category events. Participants generally build their own pavilions, making them the most extravagant and most expensive expos. Their duration may be between six weeks and six months. World Expos encompass universal themes that affect the full gamut of human experience, and international and corporate participants are required to adhere to the theme in their representations. Registered expositions are held every 5 years because they are more expensive as they require total design of pavilion buildings from the ground up. World Expos are restricted to every five years, with Specialized Expos in the in-between years. The Bureau International des Expositions (BIE) manages the Convention, with membership open to all countries. Currently, the BIE counts 170 member states, among them Austria. The next World Expo, Expo 2020 Dubai, will take place from October 20, 2020 until April 10, 2021, and will have the theme "Connecting Minds, Creating the Future".
