ZIP codes were introduced by the USPS in 1963 to improve mail sorting and delivery. The five-digit code, short for Zone Improvement Plan, pinpoints specific geographic areas.

The digits represent a region, a city or county, and a local delivery zone . Today, ZIP codes are also used to study demographics and help businesses target mailings to particular areas.

The "United States Postal Service Anthem," composed by Jack Stamp (yes, that is his real name), honors the USPS and its long-standing service to the nation. It’s a musical tribute to the dedication of postal workers and the agency’s role in American life.

The lyrics highlight the USPS’s core values: honesty, integrity, and reliability, while celebrating its impact on U.S. history and everyday citizens.

Guaranteed delivery

The USPS is legally required to deliver to every U.S. address, no matter how remote . This includes over 153 million addresses, even in hard-to-reach areas.

To meet this huge challenge, USPS uses curbside mailboxes, local post offices, and partnerships with community centers. Virtual mailbox services, such as Stable, also help remote residents access and manage their mail online.

A lot of mail

Every day, the USPS handles over 400 million pieces of mail, including 162 million First-Class items. It delivers worldwide to more than 180 countries through its Global Express Guaranteed service and processes approximately 44% of the world’s mail . That is a lot of mail, by any standard.

To manage this massive volume, USPS uses advanced automation tools and operates over 34,000 retail locations, keeping its system fast, efficient, and reliable.

Going out West

In the 19th century, the USPS played a vital role in developing the American West, providing new settlements with access to mail, supplies, and communication. Post offices and mail routes connected remote areas to the rest of the country.

This network helped settlers stay in touch with loved ones, receive news, and trade goods. Without the USPS, much of the frontier would have remained isolated.

‍ The first USPS office was established in Boston in 1775, inside a tavern associated with Benjamin Franklin , who served as the first Postmaster General. Franklin viewed mail delivery as key to America’s independence and began developing a postal network.

The office supported routes to Philadelphia and New York, and by 1789, post offices existed in all 13 colonies.

The Halibut Cove Post Office in Homer, Alaska (ZIP code 99603, in case you are interested), is unlike any other: it floats on water!

This tiny post office operates from a houseboat that’s permanently docked , serving the local community right from the harbor.

Bad handwriting department

We are not sure as to how often this happens, but it must be often. When automated equipment at a USPS processing plant cannot read a piece of letter mail, an image of the mail is captured and sent to the Remote Encoding Center (REC). At the REC, employees review the image and manually enter the address information .

The information is matched up with a valid address, the data is transmitted back to the equipment at the plant, and a barcode is printed on the letter, which can be read by the processing machines.

In 1913, shortly after the Parcel Post service began, some parents mailed their children to relatives. One baby in Ohio was sent to his grandmother just a few miles away .

The child arrived safely, but the incident led to new rules banning people from being sent through the mail.

The Moon landing (July 20, 1969)

The moment Neil Armstrong set foot on the lunar surface, he had millions of eyes upon him across millions of TV screens. Considered the television event of the decade, t he July 20, 1969 Moon landing broke records at a national and international level. Gathering an estimated 600 to 650 million viewers worldwide, "the small step for man, giant leap for mankind" was watched by around 125 to 150 million American viewers, representing around 93% of households with a TV. This record was not surpassed until the 1981 wedding of Lady Diana and Prince Charles.

"Day of Infamy" speech (December 8, 1941)

A day after the December 7, 1941 attack on Pearl Harbor by the Japanese Imperial Navy, President Franklin D. Roosevelt addressed the U.S. Congress during a joint session. His speech, which started by describing the day before as "a date which will live in infamy", was not meant to convince Congress about declaring war —which it did shortly after—but to rally a distressed and shocked nation. One of the most famous political speeches of all time, this address attracted the biggest radio audience in American history, with more than 100 million people (an estimated 81% of the adult population) tuning in.

The first Kennedy-Nixon debate (September 26, 1960)

The first of the 1960 presidential debates between Senator John F. Kennedy and Vice President Richard Nixon does not hold the record for the most viewed debate of the century (held by the 1980 Carter-Reagan debate), but it’s nonetheless a landmark event in American television. The first televised presidential debate ever, it attracted between 66 and 77 million viewers , and it is considered one of the main reasons for the shift in public opinion in favor of Kennedy. Nixon, aged 47, the leading candidate before the broadcast, appeared exhausted and pale compared to the much younger-looking and more telegenic Kennedy, aged 43.

"I have a dream" speech (August 28, 1963)

The date and location of Martin Luther King Jr.’s most famous speech were not accidental. As part of the marches in support of President Kennedy’s proposed civil rights legislation, it coincided with the centennial of the 1863 Emancipation Proclamation made by Abraham Lincoln, at whose memorial King gave his speech. Besides the massive live audience (around 250,000 people), the speech was broadcast by the three major television networks and by major radio stations in the country . Although there are no official numbers recorded, it is estimated that there were millions of viewers and listeners, including the First Family at the White House.

The War of the Worlds broadcast (October 30, 1938)

On October 30, 1938, CBS Radio Network broadcast a radio adaptation of H. G. Wells' The War of the Worlds , directed and narrated by Orson Welles. The first part of the broadcast was delivered as a realistic news broadcast, with reporters breaking the news about an alien invasion, which led part of the audience to panic and believe that an actual invasion was taking place. The episode had an estimated audience of 6 million, and it is thought that more than a million listeners believed it was a real broadcast.

FDR's first Fireside Chat (March 12, 1933)

In the 1930s, during the Great Depression, the radio became one of the main sources of entertainment and news. President Roosevelt’s Fireside Chats used the radio format as a way to connect directly with millions of weary Americans , explaining the policies that were being implemented to combat the crisis, dispelling rumors, and encouraging them to trust in the government. The friendly, informal tone of these broadcasts was highly effective in raising the nation’s morale and reducing general anxiety. With the first broadcast reaching an audience of 60 million, the Fireside Chats attracted more listeners than most of the popular radio shows, with numbers rising as America entered World War II.

Nixon’s resignation speech (August 8, 1974)

On August 8, 1974, President Nixon addressed the American public from the Oval Office to announce his decision to resign the following day as a result of the Watergate scandal and under the threat of an impending impeachment.

While the reactions of the public were mixed, the speech had an unprecedented impact and is considered one of the most important political speeches of that era.

_Roots_’ final episode (January 30, 1977)

The production and broadcast of the 1977 Roots miniseries was a milestone in itself. Only a few years before, tensions around the Civil Rights movement had shaken America, and some thought that airing a story that put the enslavement of Black people in the spotlight was a huge risk. But audience numbers proved them wrong: with around 29 million households tuning in for the first episode, the series became a cultural phenomenon that sparked conversations about race, ancestry, and American history. The final episode, with more than 100 million viewers —more than half of the U.S. population— was the most-watched TV episode of the time, and the second-most-watched overall series finale in U.S. history.

Super Bowl XVI (January 24, 1982)

Nowadays, it’s not surprising that sports events like the Super Bowl have a huge television audience, but things were different in the 1980s. Super Bowl XVI, played on January 24, 1982, in Michigan, with the San Francisco 49ers facing the Cincinnati Bengals, was watched by more than 85 million people, breaking all broadcasting records of the time .

Louis-Schmeling rematch (June 22, 1938)

When Joe Louis faced the German boxer Max Schmeling for the first time in 1936, everyone predicted that Schmeling would lose against the undefeated and rising Louis. To the world’s surprise, Schmeling won by knockout. Their rematch two years later was not only Louis’ opportunity to change the result and defeat Schmeling , but it was also charged by the increasing political tensions between Hitler’s Germany and the U.S. Besides its huge live audience at Yankee Stadium, the fight had a record audience of 70 million people in America, with an additional 30 million estimated listeners from other countries.

Friends

Who couldn’t sing along to the opening song of Friends ? "I'll be there for you" is an anthem that sparks instant nostalgia. Friends was the comfort blanket of the '90s and early 2000s: Six pals navigating life and love in a surprisingly affordable New York apartment.

Rachel, Ross, Monica, Chandler, Joey, and Phoebe. Over 52 million viewers watched the finale. For ten years, Friends made millions feel like part of the gang.

All in the Family

At the center of the 70s sitcom All in the Family was Archie Bunker, a prejudiced but lovable working-class man played by Carroll O’Connor, whose outdated views clashed with his liberal son-in-law "Meathead" (Rob Reiner).

The show tackled topics like racism, women’s rights, and the Vietnam War, and viewers loved seeing arguments they were having at home play out on screen.

Bonanza

Bonanza was the number one show between 1964 and 1967, although it aired from 1959 to 1973. Set on Ponderosa Ranch, near Lake Tahoe, Bonanza was a cowboy family drama .

Audiences fell in love with the Cartwrights: Ben, the wise patriarch, and his three very different sons. The show stood out for its lush color cinematography (very rare at the time) and storylines that combined action with moral lessons.

5

Gunsmoke

Gunsmoke, which also boasted the Western genre, remained number 1 for multiple years as well. It was one of the first TV titans to accomplish such a thing. It held the record for the longest-running primetime drama for decades. Set in Dodge City, it followed law-upholding Marshal Matt Dillon (James Arness).

When Chester, Dillon’s original deputy, left the show, fans were devastated. With over 600 episodes , Gunsmoke redefined the genre and left a permanent mark on American pop culture.

6

Jeopardy!

Image: Gift Habeshaw

Jeopardy! is a legacy that started in 1984 and is still going strong! That has led to its amassing over 10 million average viewers over the decades. How many TV shows share the same claim?

For generations, it’s been the show that makes you feel smarter just for watching (if you can outsmart the participants, that is). The answer-first, question-last format ("What is the Eiffel Tower?") became iconic, and the theme music is forever ingrained in America’s collective brain.

Who Wants to Be a Millionaire

Image: Jordon Conner

Whenever Regis Philbin asked, "Is that your final answer?" America held its breath. Who Wants to Be a Millionaire exploded onto U.S. screens in 1999 at the turn of the millennium.

The phenomenon drew 28 million viewers at its peak. The first winner, John Carpenter, made headlines for not using a single lifeline until the final question, when he used "Phone a Friend" just to call his dad and say, "I’m about to win a million dollars." That moment alone is a TV legend.

8

Survivor

Sixteen strangers marooned on a tropical island, forced to build shelter, find food, and outwit each other for a million dollars. This had a social-experiment factor that made it impossible for America to look away.

The very first season, set in Borneo, was an instant smash, with 28 million viewers. Host Jeff Probst’s fire-snuffing catchphrase ("The tribe has spoken") became iconic.

American Idol

60 Minutes

Do you remember a 60 Minutes episode that had you at the edge of your seat? Beginning in 1968, this show proved that journalism could be far more riveting than fiction.

Its secret was in smart and human storytelling, no-nonsense interviews, and a lineup of legendary correspondents like Mike Wallace, Morley Safer, and Ed Bradley.

11

The Cosby Show

Image: Francisco Andreotti

In the 1980s, The Cosby Show was the cultural touchstone. At its heart was the Huxtable family, an upper-middle-class Black household in Brooklyn, led by Cliff (Bill Cosby), an affable obstetrician, and Clair (Phylicia Rashad), a sharp attorney. Plus their chaotic five kids.

One of the most beloved moments was the family lip-syncing Ray Charles' "Night Time Is the Right Time" for Cliff’s birthday.

12

Seinfeld

Image: Rob Laughter

The premise of Seinfeld was a show about nothing . The sitcom ended up stealing the show. Between 1989 and 1998, Seinfeld cast a light on mundane life (you know, waiting in line, losing socks, awkward small talk) and turned it into comedy gold.

This "show about nothing" gave us four unforgettable New Yorkers: Jerry, George, Elaine, and Kramer. Its finale drew 76 million viewers, making it one of the most-watched episodes ever.

13

Cheers

Image: Andrea Mininni

This gem of the 80s invited America into a cozy Boston bar that felt like home. Centered around bartender Sam Malone (Ted Danson) and a colorful cast of barflies, waitstaff, and neurotic patrons, it delivered laughs, heart, and genuine warmth.

The chemistry of the ensemble was golden. And what people loved the most was that "Cheers," much like the "Central Perk" of Friends , was a place of belonging.

14

Dallas

Of course, Dallas, the ultimate primetime soap, cannot be left out of this list! This dramatic master of cliffhangers left the nation gasping. At its core was J.R. Ewing (Larry Hagman), one of TV’s most devious villains, who still had fans rooting for him.

The show became a cultural phenomenon, especially in 1980 when America asked, "Who shot J.R.?" That season finale was watched by more than 80 million people.

MAS H

Set during the Korean War, MASH was unlike anything else on TV. It mixed satire and unforgettable characters in a mobile army surgical hospital. Alan Alda led the cast as Hawkeye Pierce, backed by a beloved ensemble that included Loretta Swit, Jamie Farr, and Mike Farrell.

The show’s final episode, "Goodbye, Farewell and Amen," aired in 1983 and drew 106 million viewers. That was a record that stood for decades!
