Rather than send in the lawyers, Maiden sent itself in. The band has focused extensively on South American tours in recent years, one of which was filmed for the documentary "Flight 666." After all, fans can't download a concert or t-shirts. The result was massive sellouts. The São Paolo show alone grossed £1.58 million (US$2.58 million) alone."Iron Maiden were formed on Christmas Day 1975 by bassist Steve Harris shortly after he left his previous group, Smiler. Harris attributes the band's name to a film adaptation of The Man in the Iron Mask from the novel by Alexandre Dumas, which he saw around that time and which had a verbal connection to the iron maiden torture device."
And in a positive cycle, Maiden's online fanbase grew. According to Musicmetric, in the 12 months ending May 31, 2012, the band attracted more than 3.1 million social media fans. After its Maiden England world tour, which ran from June 2012 to October 2013, Maiden's fan base grew by five million online fans, with a significant increase in popularity in South America.
