A beautiful show takes place in Rio Carnival, with samba schools parading in the Sambadrome. Called "One of the biggest shows of the Earth", the festival attracts millions of tourists, both Brazilians and foreigners who come from everywhere to participate and enjoy the great show. Samba Schools are large, social entities with thousands of members and a theme for their song and parade. Some of the most famous samba-schools include GRES Estação Primeira de Mangueira, GRES Portela, GRES Imperatriz Leopoldinense, GRES Beija-Flor de Nilópolis, GRES Mocidade Independente de Padre Miguel, and recently, Unidos da Tijuca and GRES União da Ilha do Governador Local tourists are allowed to participate, paying ($500–950), depending on the costume, to buy a Samba costume and dance in the parade through the Sambadrome with one of the schools. The price paid is used to buy the tourist's own costume and also the costumes of the people who do not have the money to afford it. The Rio and Brazilian Carnival, is going "global" as a recent article by "Market Watch / The Wall Street Journal". which explained how the Carnival industry chain amassed in 2012 almost US$1 billion in revenues.
