Google doodle Today . Google again changing its logo in accordance with the celebrated moment. This day is 160th Anniversary of  the First World's Fair and Google doodle today is special  to remember it.

World's Fair, World Fair, Universal Exposition, and World Expo(expo short for "exposition"), are names given to various large public exhibitions held in different parts of the world. The first Expo was held inThe Crystal Palace in Hyde Park, London, United Kingdom in 1851 under the title "Great Exhibition of the Works of Industry of All Nations". "The Great Exhibition", as it is often called, was an idea of Prince Albert,Queen Victoria's husband, and was the first international exhibition of manufactured products. As such, it influenced the development of several aspects of society including art and design education, international trade and relations, and even tourism.^[1] 

Also, it was the precedent for the many international exhibitions, later called "World's Fairs", which were subsequently held to the present day. In Acapulco, New Spain (Mexico), annual fairs took place for several centuries where countries from Asia exhibited their products brought to the New World by the Spanish Royal Navy Nao de China.

The main attractions at World's Fairs are the national pavilions, created by participating countries. At Expo 2000 Hannover, where countries created their own architecture, the average pavilion investment was around €13 million.^{[citation needed]} Given these costs, governments are sometimes skeptical about participation as benefits are often assumed not to outweigh the costs. Tangible effects are difficult to measure; however, an independent study for the Dutch pavilion at Expo 2000 estimated the pavilion (which cost around €35 million) generated around €350 million of potential revenues for the Dutch economy. It also identified several key success factors for world exposition pavilions in general.^[2]

Since the entering into force of the 1928 Convention relating to International Exhibitions, the Bureau International des Expositions(BIE; English: International Exhibitions Bureau) has served as an international sanctioning body. BIE-approved fairs are divided into a number of types: universal, international or specialized. They usually last between three weeks and six months.
