This year's Brasileiro "has lost almost half a million fans" compared to the '11 edition, according to Lucas Reis of FOLHA DE S. PAULO. Through 30 weeks of the championship, 3.7 million fans have paid to attend games. At this time in the '11 edition, 4.2 million had purchased tickets to games. This means that for every game of this season's Brasileiro, "attendance has been down 1,500." The average attendance through 30 weeks has dropped from 14,191 to 12,649. The main reason for this has been all the construction taking place in stadiums as the country prepares for the 2014 World Cup. But the drop in attendance has not "meant a decrease in ticket revenue." Through 30 weeks of the '11 Brasileiro, R$85.5M was generated through ticket sales. During this year's edition, ticket sales revenue is up to R$90.5M ($44.6M). The explanation is a "readjustment in the average value of tickets." On average, a fan has paid R$23.9 ($11.8) for a ticket this year compared to R$20.1 in '11. The numbers show an increase of 18.9%. According to Brazil's Consumer Price Index (IPCA), inflation in the 12 months that separated the start of the '11 and '12 Brasileiro was 4.99%. Corinthians FC and Gremio FC are the only two clubs with an average attendance of more than 20,000 this season (FOLHA DE S. PAULO, 10/18).
