When you think of the word fair, you think of something like a county fair with food, amusement rides, and games. But worlds fairs/expositions are more about showcasing achievements. Worlds fairs were more popular back in the 20th century. They focused on inventions such as architectural, artistic, and technology. Today, they focus more on other things such as improving the hosts' countries' image. I find it interesting how at the fairs they build buildings for it and then showcase them. Some of the buildings built for the fairs are still standing today, which is something that is very interesting.
