The World Expo is an international exhibition that is considered a symbol of industrialization, as well as an open platform for demonstrating technical and technological achievements.Since the signing of the Convention on International Exhibitions in 1928, the International Bureau (BIE, Bureau International des Expositions) of exhibitions has been the regulator of three types of exhibitions: universal, international and specialized.These exhibitions last 3-6 months. The tradition of holding international exhibitions originated in the light of the French national exhibitions, which culminated in the International Exhibition of 1844. The first world exhibition was held in Hyde Park in London at the initiative of Prince Albert of Saxe-Coburg Gotha.The main attraction of the exhibition was the Crystal Palace, built of metal and glass by Joseph Paxton. Currently, there are two main types of exhibitions: registered and recognized. Registered exhibitions are the largest events in terms of scale. Previously, registered exhibitions were called “universal exhibitions”. Exhibitions of this type are held every 5 years. Recognized exhibitions are smaller in volume and cost, shorter in duration (from 3 weeks to 3 months).Participants’ costs are lower, as they can rent an already built exhibition hall from the organizer.Then they have the opportunity to add their own colors, design, etc. from the outside of the object and fill it with products.
