On Saturday, officials of the company that owns the Ringling Bros. and Barnum & Bailey Circus announced that it will close in May, ending a 146-year run that dates back to a time before automobiles or airplanes or movies, when Ulysses S. Grant was president and minstrel shows were popular entertainment. What killed the circus? There are many suspects: increased railroad costs. Costly court battles with animal rights activists that led to an end to elephant acts - and the fact that some people didn’t want to see a show without elephants.In a press release, animal rights group PETA celebrated the circus’ demise. “Thirty-six years of PETA protests, of documenting animals left to die, beaten animals, and much more, has reduced attendance to the point of no return,” PETA’s statement read. “All other animal circuses, roadside zoos, and wild animal exhibitors, including marine amusement parks like SeaWorld and the Miami Seaquarium, must take note: society has changed, eyes have been opened, people know now who these animals are, and we know it is wrong to capture and exploit them.” But mostly, in an era of Pokemon Go, online role playing games and YouTube celebrities, the “Greatest Show on Earth” doesn’t seem so great. “It’s been through world wars, and it’s been through every kind of economic cycle and it’s been through a lot of change,” said Kenneth Feld, chairman and CEO of Feld Entertainment, owner of the Ringling Bros. “In the past decade there’s been more change in the world than in the 50 or 75 years prior to that. And I think it isn’t relevant to people in the same way.” Just this week, the circus made headlines when it announced that a woman would be ringmaster for the first time in the show’s 146-year history.
