The first entry on the list showcases the inventor of probably the most popular waiting-call tunes in history, Scott Joplin, the "King of Ragtime" himself. He composed over 40 ragtime pieces, one ragtime ballet, and two operas. One of his first and most popular pieces, the "Maple Leaf Rag," became the genre's first and most influential hit, later recognized as the quintessential rag.

Joplin considered ragtime to be a form of classical music meant to be played in concert halls and largely disdained the performance of ragtime as honky-tonk music, most common in saloons.

Blues - W.C. Handy

Blues music can’t be traced to a single individual, but William Christopher Handy can definitely be identified as a founding figure in the genre. He was an American composer and musician who referred to himself as the "Father of the Blues."

One of many musicians who played the blues, Handy did not create the blues genre but was one of the first to publish music in the blues form , thereby taking the blues from a regional music style (Delta blues) with a limited audience to a new level of popularity.

3

Jazz - Buddy Bolden

Charles Joseph "Buddy" Bolden was an American cornetist who was regarded by contemporaries as a key figure in the development of a New Orleans style of "jass," which later came to be known as jazz. Bolden was known as "King" Bolden, and he was known for his loud sound and improvisational skills, and his style had an impact on younger musicians.

Many early jazz musicians credited Bolden and his bandmates with having originated what came to be known as jazz , although the term was not in common musical use until after Bolden was musically active. At least one writer has labeled Bolden as the father of jazz.

Country - Jimmie Rodgers

Widely regarded as the "Father of Country Music," James Charles Rodgers was an American singer-songwriter and musician who rose to popularity in the late 1920s. He is best known for his distinctive yodeling , which is a singing style imported from the Alps.

He has been cited as an inspiration by many artists and he has been inducted into multiple halls of fame. By 1927, he stopped working for the railroad due to health issues and decided to focus on his music career.

5

Soul - Sam Cooke

Known as "the King of the Jukebox," Louis Thomas Jordan was an American saxophonist, multi-instrumentalist, songwriter, and bandleader who was popular from the late 1930s to the early 1950s.

Jordan blueprinted the map of classic R&B, urban blues , and early rock-and-roll genres with a series of highly influential 78-rpm discs released by Decca Records. These recordings presaged many styles of Black popular music in the late 1940s, 1950s, and 1960s and exerted a strong influence on numerous leading performers in these genres.

Best known as "Chuck," Charles Edward Anderson Berry was an American singer, guitarist, and songwriter who pioneered rock and roll music. Nicknamed the "Father of Rock and Roll," he refined and developed rhythm and blues into the major elements that made rock and roll distinctive , writing lyrics that focused on teen life and consumerism and developing a musical style that included guitar solos and showmanship.

He recorded "Maybellene"—Berry's adaptation of the country song "Ida Red"—which sold over a million copies and reached number one on Billboard magazine's rhythm and blues chart.

Disco music was becoming increasingly popular in the early 1970s, but according to many historians, it was Donna Summer’s "Love to Love You Baby" that became the first "official" disco release .

The song did not have an immediate American release; it started its life with moderate success in Europe before finally gaining traction and being launched in the U.S., where it became her first number-one hit on the Hot Dance Club Play Chart.

10

Rap - DJ Kool Herc

While this name might not be as instantly recognizable as those from the previous entries, it certainly deserves to appear and close the list, as it is often cited as responsible for the birth of an extremely popular music genre. Clive Campbell, better known by his stage name DJ Kool Herc , is a Jamaican American DJ credited with being one of the f ounders of rap music in New York City in 1973.

Nicknamed the "Father of Hip-Hop," Campbell began playing hard funk records typified by James Brown. He isolated the instrumental portions of the records, emphasizing the drum beat—the "break"—and transitioned from one break to another. Campbell's announcements helped lead to the syncopated, rhythmically spoken accompaniment now known as rapping.

It was originally an advertisement

Image: Emma Timmers

Have you ever wondered why the sign exists at all? After all, not many cities display neighborhood names on a nearby hill . When the sign was first erected in 1923, it was simply a billboard promoting a real estate development, and it was supposed to stand for only about 18 months.

2

It used to be longer

Image: Sarah Sheedy

The sign originally read "Hollywoodland" , the name of a new housing development that promised wealthy buyers unique views of the sunny hills of Los Angeles. So, they stuck a gigantic sign on Mount Lee. Just temporary , they said. Just for marketing .

Over 20 years later, the district had become more culturally relevant than the housing development, but people had grown used to the sight by then. So, they decided to let go of four letters. Each cost a fortune to maintain anyway.

3

It used to be bigger

Image: Eliot

The original "Hollywoodland" sign was massive. Each letter stood 43 feet tall and stretched 30 feet across. They were made from thin metal panels slapped onto wooden frames and held up by telephone poles.

It dazzled from afar, but up close, it was a wobbly mess . The construction was so flimsy that by the 1930s, some of the letters were already tilting, cracking, or sliding out of place.

4

It’s appeared in more movies than most actors

Image: Ramaz Bluashvili

Doesn’t that fact make you giggle? It’s not Bette Davis, and it’s not Anthony Hopkins—it’s the Hollywood Sign that has more movie credits .

Aliens have blown it up. Earthquakes have toppled it. Sharks have flown right through it. But it’s also been the backdrop for kisses, chases, and friendship montages. Directors love it because it screams "L.A." in three seconds flat.

5

Technically, it’s not in Hollywood

Image: RDNE Stock project

The Hollywood Sign doesn’t actually sit within the neighborhood of Hollywood—it stands atop Mount Lee, inside Griffith Park, which is managed by the City of Los Angeles . So while it may say Hollywood , it’s not technically in Hollywood.

6

It’s been rebuilt twice

Image: Gerald Schömbs

By the 1940s, the city stepped in and gave the sign a minor facelift. After the crumbling "LAND" was scrapped, the remaining letters were patched up.

But by 1978, the sign was in serious trouble again—rusted, leaning, and on the verge of collapse, it was deemed beyond repair. This time, Hollywood did what it does best: rebooted it entirely . A new sign was built from scratch, using steel beams and concrete foundations.

7

Celebrities "sponsored" letters

Image: Joseph Menjivar

When Hollywood cried for help in the late ’70s, it was Playboy founder Hugh Hefner who stepped in. The city didn’t have the funds to rebuild the sign, so Hefner threw a glitzy fundraiser to find sponsors for each of the nine letters, at $27,777 apiece.

And it worked. Alice Cooper funded the "O" in memory of Groucho Marx. Gene Autry sponsored the second "L." Even Warner Bros. chipped in.

8

No public trail leads directly to it

Image: Venti Views

Perhaps you’ve heard a disappointed tourist complain about this before: You can hike near it. You can pose below it. But actually walking up to the letters is a no-go. The trails in Griffith Park will get you close, with plenty of Instagram-worthy views. But conservation efforts mean you’ll never legally stand between the "L"s.

One reason is that decades ago, it was easier to reach the sign—and some fans even climbed the letters.

9

The land surrounding it was once nearly sold for development

Image: izayah ramos

In the early 2000s, developers had their eyes on the land behind the sign. The plan was to construct luxury homes in the hills with killer views. But the public response was pure outrage.

Enter Hugh Hefner (again), along with celebrities and conservation groups , who raised over $12 million to save the land. Today, those hills are permanently protected.

10

It has its own security team

Image: Lukas Geck

As mentioned earlier, you can’t get a selfie next to the "H" because the sign is off-limits to the public. It’s monitored 24/7 with infrared cameras, motion sensors, microphones, and regular patrols. Some hikers still try their luck, but trespassing can lead to citations, fines, and in some cases, arrest.

11

It’s copyrighted; you can’t just slap it on a T-shirt

Image: Simon Ray

Call a lawyer before you print the Hollywood Sign on your merch. Some trademark rights to the sign are owned by the Hollywood Chamber of Commerce. That means any commercial use—like shirts, mugs, or movie scenes— requires a license . Even photographers have to tread carefully.

12

Helicopters were used to move the letters

Image: Somchai Kongkamsri

The letters have been helicoptered off before. In 1978, when the new sign was being installed, the old, rusted letters had to go. But since you can’t exactly wheel 50-foot steel slabs down a hiking trail, helicopters came to the rescue.

One by one, the original letters were airlifted off the mountain in a strange, sky-high farewell. It was quite an event, and crowds gathered to watch.
