We’ll begin with one of the first fads invented right here in America. The 1920s in America were characterized by a period of prosperity and well-being that resulted in a dynamic and distinct cultural rise in major American metropolises. There’s a reason why this period was known as "The Roaring 20s": It signified an upheaval in American music, arts, and fashion.

The 20s saw the birth of avant-garde art forms like jazz music, as well as groundbreaking novels by authors like F. Scott Fitzgerald and Ernest Hemingway. This era is also remembered for the surge of the "Flapper" subculture: Modern, young women with a more carefree attitude toward entertainment.

Who do you think about whenever you think of the word "pin-up model"? Chances are your answer is Marilyn Monroe or Betty Grable: After all, they both got their start as pin-up models, portrayed in thousands of mass-produced photographs. However, these actresses helped cement the notion of what defines a pin-up model, now considered to be an essential icon in American pop culture history.

Pin-ups defined the aesthetic of an entire period, present in everything from movies to advertisements. Not only that, pin-up models were often depicted on the side of American fighter planes during World War 2, helping raise the morale of our troops.

Although the word "greaser" definitively got its start as a derogatory term for this subculture, it ended up being the name of one of America’s most beloved periods. The 1950s are still revered as a golden age by millions of Americans, particularly because of the surge of many icons that make our country so wonderful: Things like Cadillacs, Rock N’ Roll music, and soda fountains were all born in this era.

In that sense, the "Greaser" look was heavily influenced by musicians and actors like Elvis Presley and James Dean. Greasers would showcase their fast motorcycles, stylish hairstyles, and leather jackets wherever they went. By the 1970s, this style was so well-known that it provided the basis of one of America’s favorite TV characters: Fonzie, perhaps now considered the quintessential greaser.

The Hippie movement is synonymous with 1960s America: This subculture influenced almost every art form during this period, from music to television, film, and literature. While it is nowadays mostly looked at as an aesthetic or cultural movement, the influence of hippies in American politics and society shouldn’t be overlooked.

Perhaps the biggest representatives of the hippie movement are those groundbreaking bands and musicians aligned with this movement, like Jimi Hendrix, Janis Joplin, or Jefferson Airplane. Hippies were also characterized by their groundbreaking fashion, which featured bell-bottom jeans, sunglasses, and colorful shirts.

Speaking of hippies, let’s take a little detour and focus on an American artistic movement that laid the foundation from which the hippie movement emerged. Much like with "greaser," the term "beatnik" was first coined as an insult, aimed at followers of the "Beat Generation," a literary movement that included names like Jack Kerouac or William S. Burroughs.

The beatnik subculture had a defining image, often exaggerated by detractors: Think about the caricature of a modern poet, complete with a black turtleneck, beret, and bongos, and you’ll be thinking about a stereotypical beatnik. Regardless, historians believe that the term "hippie" comes from "hipsters," which is a term first used to describe the beatnik subculture.

Fashion during the 1980s can be best summed up by this phrase from Charles Dickens's "A Tale of Two Cities": "It was the best of times, it was the worst of times." While it can’t be denied that this decade brought forward groundbreaking styles to music, films, and culture, it should also be noted that some of these changes were extreme, to say the least. At the end of the day, whether the 80s were good or bad will ultimately depend on who you are asking.

Personally, we would like to focus on those 80s things that we absolutely love: Things like synthesizer music, mullet hairstyles, and neon-bright clothing. This decade was also the birthplace of several subcultures, including the post-punk, preppy, and new-wave movements.

If the 70s and 80s were characterized by their loud and flamboyant styles, the 90s were defined by a more minimalist approach: Bands like Nirvana or Pearl Jam helped promote the "grunge" aesthetic, which featured simple items of clothing like jeans, flannel shirts or hoodies.

Although definitively minimalist, the 90s were also the birthplace of subcultures like the goth movement. During this era, numerous extreme sports like skateboarding gained popularity, in line with this decade’s alternative outlook on culture.

Ready to dance "The Hustle"? The late 60s and early 70s were determined by the emergence of one of America’s most remembered subcultures. While disco music first appeared in New York City and Philadelphia, it quickly swept over the nation: Think of a tornado filled with disco balls, roller skates, and nightclubs, and you might be able to paint a picture of how influential this subculture was.

Although disco got its start in iconic nightclubs like Studio 54, it soon expanded to other mediums like movies and television. Most notably, shows like "Soul Train" helped promote this genre’s appeal, while films like "Saturday Night Fever" cemented the ultimate aesthetic of the disco subculture.

We have now arrived at our modern times! The advent of the internet represented such a groundbreaking innovation in our everyday lives that it stands to reason that the digital age also influenced many of our fads and movements. The late 2000s and early 2010s were determined by this new massive access to information, which completely changed the way we consume culture and entertainment.

In that sense, this new, instant way to share information immediately meant that culture was now not only limited to geographical locations: Your favorite band or fashion icon could easily live on the other side of the world. This cultural exchange resulted in a rich and diverse movement, which is still developing to this very day.

We have reserved the final entry on this list for the many objects that defined each of these decades. It is sometimes easier to picture an era through a specific item: Think about the 50s and their timeless jukeboxes, or the 90s and the above-mentioned flannel shirts.

In that sense, we have selected a few of our top picks. Some, like the Hula Hoop or the Frisbee, have truly transcended time: Although they were created decades ago, they are still thoroughly enjoyed by children and adults alike. Time hasn’t been that kind with others, though, like with the now practically extinct Tamagotchi. This digital pet was all the rage during the late 90s and early 2000s, but it ultimately fell into obscurity thanks to other digital mediums.
