Why Do Radio Stations Begin With 'K' or 'W'?

Radio might not be quite the media force it once was, but there are still thousands of stations around the country, and the call letters for almost every one of them begin with either "K" or "W."

Why? Because the government said so.

In the days of the telegraph, operators started the practice of using short letter sequences as identifiers, referring to them as call letters or call signs. Early radio operators continued the practice, but without a central authority assigning call letters, radio operators often chose letters already in use, leading to confusion.

To alleviate the problem, the Bureau of Navigation (part of the Department of Commerce) began assigning three-letter call signs to American ships in the early 1910s. Ships in the Atlantic and Gulf of Mexico got a K prefix; in the Pacific and the Great Lakes, a W. The precise reasons for choosing these two letters, if there were any, are unknown (bureaucracy works in mysterious ways). At the 1912 London International Radiotelegraphic Convention, ranges of letters were assigned to each of the participating nations and the U.S. was told to keep using the W and most of the K range. (Military stations used N.)

When the federal government began licensing commercial radio stations soon after, it had planned to assign call letters to the land-based stations in the same way. Somehow, things got flipped during implementation, though, and Eastern stations got W call signs and the Western ones got Ks. Where exactly does the Bureau of Navigation draw the line between East and West? For a while it ran north along state borders from the Texas-New Mexico border, but shifted in 1923 to follow the Mississippi River.

Some areas, however, might have both a K and W station in the same vicinity. Why? When the dividing line switched, some stations were made to change their call signs, while others weren't. For about a year in the 1920s, the Bureau of Navigation decided that all new stations were going to get a K call sign no matter where they were located. Still other exceptions were made by special request, station relocations, ownership changes, and even human error.

As for the rest of the call sign: That sometimes includes the station (ABC, NBC), but can also be an acronym. WGN stands for "World's Greatest Newspaper" (as it was considered the Chicago Tribune's radio station) while Chicago's WTTW is "Window to the World." But nothing beats St. Louis sports station KRAP, which gave itself the very self-aware label in 2014. “Our signal is KRAP,” reads their website. “Our studios are KRAP. Even our staff is KRAP.”

Why Are We So Scared of Clowns?

With the recent box office-smashing success of Stephen King's It, it’s safe to say that coulrophobia (fear of clowns) isn’t a fringe phenomenon. The colorful circus performers are right up there with vampires and werewolves on the list of iconic horror villains. But unlike other movie monsters, clowns were originally meant to make kids laugh, not hide under their beds in terror. So what is it about clowns that taps into our deepest fears?

According to Yale doctoral candidate Danielle Bainbridge, the unsettling clown stereotype goes back centuries. In the inaugural episode of the PBS digital series Origin of Everything, Bainbridge explained the long history of this pervasive part of our culture.

Before clowns wore floppy shoes and threw pies at each other’s faces, early versions of the performers could be found in royal courts. The court jester wasn’t evil, but he was the only person in the kingdom who could poke fun at the monarch without fear of (literally) losing his head. The fact that fools didn’t fall within the normal social hierarchy may have contributed to the future role clowns would play as untrustworthy outsiders.

From the medieval era, clowns evolved into the harlequins of 16th-century Italian theater. Again, these weren’t bloodthirsty monsters, but they weren’t exactly kid-friendly either. The characters were often mischievous and morally bankrupt, and their strange costumes and masks only added to the creepy vibes they gave off.

Fast-forward to the 19th century, when the white-faced circus clowns we know today started gaining popularity. Unlike the jesters and harlequins that came before them, these clowns performed primarily for children and maintained a wholesome image. But as pop culture in the 1970s, '80s, and '90s showed us, that old perception we had of clowns as nefarious troublemakers never really went away. Steven King’s It, the cult classic Killer Clowns From Outer Space (1988), and that scene from Poltergeist (1982) all combined these original fears with the more modern association of clowns with children. That formula gave us one of the most frightening figures in horror media today.

Why Do We Call a Leg Cramp a Charley Horse?

If you’re unlucky enough to have experienced a charley horse—a painful muscle spasm or cramp in your leg—then you may have found yourself wondering what this nonsensical phrase even means. Who is this Charley character? Where did he come from? And what does he know about my pain?

Like the words flaky and jazz, this term likely entered the language from the baseball field. While the idiom’s etymology isn’t 100 percent certain, archived newspaper articles suggest it was coined by a baseball player in the 1880s. We just don’t know which player said it first, or why.

According to a January 1887 article in the Democrat and Chronicle, the phrase was well-known to baseball players at the time—but to the average person, charley horses were as enigmatic as “an Egyptian hieroglyphic.” That year, charley horses were mentioned in a slew of newspapers across America, and some attempted to tackle the phrase’s murky origin. “Nearly every sporting journal gives a different version as to how the term charley horse originated in baseball circles,” the Oakland Daily Evening Tribune reported at the time.

The likeliest tale, according to the paper, centered around John Wesley "Jack" Glasscock, a shortstop who at the time was playing for Indianapolis. At some point a few years earlier, the player had strained a tendon in his thigh during a game and afterwards went home to his farm, where his father looked after a lame old horse called a "Charley horse." When the senior Glasscock saw his son limping along, he reportedly exclaimed, “Why, John, my boy, what is the matter; you go just like the old Charley horse?” John supposedly shared the funny turn of phrase with his teammates, and from there it spread. Similar accounts were reported in other newspapers, but they were attributed to various other players.

Other reports say the phrase has nothing to do with a live animal, but rather the fact that an injured player, while running, resembles a rocking horse or a child riding astride a wooden hobby horse.

The New Dickson Baseball Dictionary by Paul Dickson details a few other theories. In two versions of the same basic tale, Orioles or Chicago Cubs players went to the races and bet on a horse named Charlie who "pulled up lame in the final stretch." The next day, a player pulled a tendon in his leg and was said to resemble “our old Charlie horse.”

Alternatively, its origin may relate to an old workhorse that was tasked with pulling a roller across the infield. “Often in the 1800s, old workhorses kept on the grounds of ballparks were called Charley. The movements of the injured, stiff-legged ballplayers were likened to the labored plodding of these old horses, and the injury itself eventually became known as a ‘charley’ or ‘charley horse,'" Tim Considine wrote in 1982's The Language of Sport.

It also appears that charley horse originally implied a much more serious injury—or perhaps there was a bit of hysteria surrounding a condition that seemed new and scary in the late 19th century. The Democrat and Chronicle described a charley horse as a “giving way of one of the small tendons of the leg” and said an injured baseball player might need an entire season to recover. Another article from 1887 said ballplayer George Van Haltren’s relatives were worried he would get a charley horse, “although they do not know what that is.” He was said to have been “very fortunate” because he had “not yet encountered the terrible charley horse.”

For comparison, Healthline.com now says charley horses “are generally treatable at home” by stretching, massaging, or icing the afflicted area, although the muscle pain can linger for up to a day in some cases. So there you have it. We may never know the exact etymology of the charley horse, but the next time you get a sharp pain in your leg, you can thank an old-timey ballplayer for making your struggle sound so silly.
