Considering that the Olympics have thousands of years of tradition behind them, it's easy to get the perception that they've always been conducted more or less the same way.
However, the events that participants along the world strive to compete in have actually changed a great deal at various points throughout history. Obviously, you're not likely to find many people who believe that the Olympics of Ancient Greece featured sports that hadn't been invented yet like hockey and basketball but it's not unheard for events to be taken away as well.
For instance, from 1912 to 1948, the Olympics had five categories in which you could conceivably win a gold medal for art.
But while the pandemic means we haven't had any Olympics to watch this year, you'll likely find some fascinating differences from what you're used to when they come back.
