Stuff has gotten much, much bigger in the past 100 years.
2015: The biggest stadium in the world is the Rungrado 1st of May Stadium in Pyongyang, North Korea. It’s used for state-sanctioned entertainments as well as the national soccer team, and it seats 150,000 people. (The biggest stadium in the U.S. is Michigan Stadium, where the University of Michigan Wolverines play football to a mere 107,601 fans.)
1915: College football was just as popular then as it is now, although it was limited to the East Coast and upper Midwest. The biggest teams in the sport were Harvard and Yale. It’s not surprising, then, that the Yale Bowl in New Haven, Connecticut, which opened in 1914, was the biggest stadium in operation at the time, seating 70,896 people.
2015: Today, the tallest building on earth is the Burj Khalifa, a skyscraper that finished construction in Dubai in 2010. It’s 2,717 feet tall, dwarfing the 2003-2010 record holder, the Taipei 101 in Taipei, a mere 1,671 feet.
1915: A century ago, the tallest building in the world was the Woolworth Building in New York City. Opened in 1913, it stood 791 feet tall. It’s about one-quarter the height of Burj Khalifa.
2015: The Tokyo metropolitan area is home to 26.4 million people, easily making it the most populous city on the planet.
1915: One hundred years ago, London was home to 6.6 million people, or about one-quarter the number of people who live in and around present-day Tokyo.
