A circus is most commonly a traveling company of performers that may include acrobats, clowns, trained animals, trapeze acts, hoopers, tightrope walkers, jugglers, unicyclists and other stunt-oriented artists. The word also describes the performance that they give, which is usually a series of acts that are choreographed to music. A circus is held in an oval or circular arena with tiered seating around its edge; in the case of traveling circuses this location is most often a large tent called the big top. In the 1960s and 1970s, the circus began to lose popularity as people became more interested in alternative forms of entertainment. Some circuses have stayed afloat by merging with other circus companies. There are numerous circuses that maintain a mix of animal and human performers, these include Ringling Brothers and Barnum and Bailey Circus, the Moscow State Circus, Circus Krone from Munich, Circus Royale from Australia and the Big Apple Circus. Circus Circus is a Las Vegas circus themed casino and the largest permanent big top in the world also presents human and animal performances. Cirque nouveau / New Circus is a performing arts movement that developed in the 1970s, simultaneously in France, Australia the West Coast of the U.S. and the U.K . There are no animals used in this type of circus and influences are drawn as much from contemporary culture as from circus history. Examples include Circus Oz forged in Australia in 1977 from SoapBox Circus and New Circus, both founded in the early 70's, The Pickle Family Circus founded in San Francisco in 1975, and more recently Circus Burlesque from the U.K in 1980 and Nofitstate circus[6] in 1984 from Wales, Cirque du Soleil founded in Quebec, Canada in 1984, Archaos in 1986, Club Swing in 1994, through to more recent examples such as Quebec's Cirque Éloize, Les Sept Doigts de la Main, and the West African (French Guinea - Guinée) Circus Baobab in the late 90's. The form includes other circus troupes such as the Le Cirque Imaginaire, later renamed Le Cirque Invisible both founded and directed by Victoria Chaplin, granddaughter of Charlie Chaplin, the Tiger Lillies, Circus Monoxide, Acrobat, Dislocate, RANGA Circus (now CIRCA), and Throwdown, while The Jim Rose Circus and The Happy Sideshow are both interesting takes on the sideshow.

U.S. Company PURE Cirkus  under the Genre of Cirque Noir, was founded in 2004, and in Northern England, (United Kingdom), combining punk, rap, dance music, comedy, and daring stunts, Skewed Circus delivers "pop-circus" genre entertainment to young urban audiences who have not had the opportunity to visit traditional circuses. Circuses from China, drawing on Chinese traditions of acrobatics, like the Chinese State Circus are also popular touring acts. The International Circus Festival of Monaco has been held in Monte Carlo since 1974 and was the first of many international awards for circus performers. There were always circuses in Kiev — in particular in 1903 there was a circus where Krutikov worked with  horses. Before 1875 there had been no permanent building of circus in Kiev, but only temporary wooden buildings that were demolished after several months of work. Especially known was clown and animal trainer Mikhail Zollo. Russian tsar Nikolay II was so impressed with Zollo's performance that he presented him his own golden watches. Mikhail Zollo had its own circus troupe with about 200 animals. There was a circus on the corner of Sagsaganskogo street and Bolshaya Vasilkovskaya after the war. Such famous masters as Durov, Zollo and Kio performed there. Russian tsar Nikolay II was so impressed with Zollo's performance that he presented him his own golden watches. Mikhail Zollo had its own circus troupe with about 200 animals.
