The Diner en Blanc is regarded as an exclusive upper-class event with no commercial or political backgrounds. The number of participants, however, is now in the thousands.
As today Dîner en blanc is known, based on private initiative, through networks of friends and family picnics organized mass of people dressed in white in prominent urban locations. The starting point of the phenomenon was Paris. Meanwhile there are similar events held today in several other cities, including in Montreal, in Munich, Berlin, Frankfurt am Main, Darmstadt, Zurich, Cologne and Hanover.
As source of the event is called the summer 1988, when a certain Francois Pasquier moved spontaneously his overcrowded private garden party in the nearby Bois de Boulogne . It was a great hit. As a result, he arranged every June at a joint, not registered to the police so the picnic is held secretly in a public place in Paris. Mandatory for all participants is to wear completely white clothes from head to toe. Everybody has to bring their own tables and chairs then they are assembled into long panels with all participants and it is also obligatory to bring a three-course menu and cold drinks. Served as venues including the Place de la Concorde, the terrace of the Palais de Chaillot and the courtyard of the Louvre. The 20 thst Anniversary of the event was held in the avenues of the “Champs-Élysées”. This year in June 17 it took place at Notre Dame.
More recently the idea spread in the German speaking countries. On 29 May 2010 was the first example, Diner en Blanc in Berlin on Bebelplatz with about 400 participants and on 1st of July 2010 gathered about 500 guests all in white in the Munich Hofgarten. However in Hanover the dinner in white has been held since 2008, usually changing constantly in places that are kept secret until the last. Usually remain hidden from the organizers, because events of this magnitude usually not without conditions (toilets, fees, garbage collection, etc.) may be performed. The idea has since spread into a worldwide, picked up by the son of the founder, Aymeric Pasquier, in Montreal. This will attempt to build a network effect in which all the cities together.
The original Diner en Blanc is without any commercialism. By event organizers, champagne producers and other companies now in some professional events and catering are offered admission. So far this form has been rejected by the founders of the Diner en Blanc.
The flash mob phenomenon is a bit similar to the diner en blanc phenomenon. Flash mob is a group of people who assemble suddenly in a public place, perform an unusual and sometimes seemingly pointless act for a brief time, then disperse, often for the purposes of entertainment and/or satire. Flash mobs are organized via telecommunications, social media, or viral emails. The term, coined in 2003, is generally not applied to events and performances organized for the purposes of politics (such as protests), commercial advertisement, publicity stunts that involve public relation firms, or paid professionals.
