These historic and modern photos capture the real differences between the way events used to be and how they are today.
The first official gay pride march moves through London surrounded by police for their protection. During the 2014 LGBT London pride parade, marchers were flanked by supporters instead.
The first International match at Wimbledon drew a few dozen upper class spectators in 1883. This match at the 2014 games attracted a few more.
The first Rockefeller Christmas tree on the construction site of the tower in 1931 and the latest in 2013.
The first Glastonbury festival in 1970, when 1,500 people paid £1 each for a ticket and free milk. In 2014, 135,000 people paid £225 and beer took the place of milk.
The first World Series in Pittsburgh in 1903, an overflowed crowd swarmed the field and play continued. The people lined up in an arc in the outfield became the fence. The 2014 World Series final was slightly more organised.
The first photo taken from space, a camera was strapped onto a V2 rocket fired straight up in 1946. And the Aurora Australis from the International Space Station in 2013.
The opening ceremony of the first official Paralympic Games, held in Rome in 1960. 400 athletes from 23 countries competed in eight disciplines. At London in 2012, 4,300 athletes from 164 nations took place in 20 sports to the fanfare they deserved.
Sir Edmund Hillary, the first climber to reach the summit of Mt Everest in 1953. As can be seen by this traffic jam in 2013, a few more people attempt now that we have far better equipment.
An aerial view of the 1930 World Cup final in Montevideo, Uruguay. Only 13 teams entered because of the difficulty of getting to South America at the time. Uruguay defeated Argentina 4-2. At the games in Brazil this year, 209 countries were eligible to enter.
The first photograph of the moon, taken in 1839. The first photograph of Earth taken from the moon in 1969. And, a picture of both the Earth and moon from China's Chang'e 5-TI satellite in 2014.
Three men participate in the marathon at the first modern Olympics in 1896, only 16 nations were allowed to compete. In the 2012 marathon in London, there were 206 nations in attendance.
The first neon sign is installed on the Las Vegas strip in 1941. Now, you're pretty much blinded if you move within 5 miles of the Nevada Desert.
The crowd that gathered for the first modern Olympic Games, held in Athens in 1896, pales in comparison to the crowd in London during the 2012 Olympics.
The upper class of New York escape the busy streets above on New York's first subway in 1904. Now, the underground is no longer the choice of the richest and just as busy as above ground.
Western Berliners look on as work begins on the Berlin wall in 1961. This year, united Berliners celebrated the anniversary of the fall of the wall and marked it's former path with illuminated balloons.
Bill Murry as the first guest on the David Letterman Show in 1983. The pair shared on the same stage again in 2014, along with a star of this generation, Lady Gaga.
Boston Marathon organisers attempt to stop Kathrine Switzer from running the mens-only race in 1967. In 2014, almost as many women qualified for the marathon as men did.
In 1903, the Wright brothers took this photo because they feared no one would believe they had created a vehicle that could fly for 59 seconds over 852 feet. In 2014, a probe which had travelled 4 billion miles landed on a comet - we believed it.
A French soldier whose face was mutilated in World War One is fitted with a prosthetic mask in 1918. Less than a century later in 2011, doctors carried out the first full face transplant on Dallas Wiens who lost all of his face in an accident.
We've certainly got more daring over the years too. In 1894, Otto Lilienthal made the first glider flight. In 1901, Annie Edson Taylor become the first person to survive a trip over Niagara Falls in a barrel. And, in Felix Baumgartner took a plunge from the stratosphere - 24 miles above Earth.
