Instant replay in sports has sparked about as much controversy as it has eliminated since the feature was introduced more than 50 years ago, but it's hard to imagine watching games today without it. Here's a look back at the men behind the invention and how various sports have incorporated the use of instant replay through the years.

Instant Replay Pioneer

George Retzlaff, a Toronto-based producer for the Canadian Broadcasting Corporation's wildly popular "Hockey Night in Canada," used a hot processor to produce a wet-film replay of a goal during the 1955-56 season.

Retzlaff annoyed the advertising agency that sponsored the show by not providing advanced notice that he was planning to employ this innovative technique, and the program's other production studio in Montreal didn't have the equipment to replicate the method, so Retzlaff never used it again. Still, Retzlaff's not-quite-instant replay was a seminal moment in the history of sports broadcasting and ranks No. 24 on the CBC's list of the greatest Canadian inventions of all time.

The Origins of Videotape-Based Replay

Tony Verna, who was hired as a director at CBS by future Dallas Cowboys general manager and NFL innovator Tex Schramm, had experimented with videotape while working the 1960 Rome Olympics. Verna spent a lot of time directing football games and was determined to find an interesting way to fill the lulls in the action between snaps. He also wanted to be able to show viewers the game that was taking place away from the ball on a given play. "If it didn't happen on TV, it didn't happen," Verna told Joe Starkey of the Pittsburgh Tribune-Review in 2003. Verna eventually developed a system—using audio tones added to the cue track of the videotape—that enabled him to rewind to the point just before the ball was snapped on the previous play for instant playback.

Instant Replay's Big Debut

Verna debuted his instant replay technique on December 7, 1963, during the annual Army-Navy football game. While technical glitches with the 1,200-pound videotape machine that Verna had transported to Philadelphia's Municipal Stadium prevented him from using the feature in earlier in the game—one replay camera was focused on Navy quarterback Roger Staubach and another on Army quarterback Rollie Stichweh throughout the day—it was finally introduced on Stichweh's one-yard touchdown run in the fourth quarter. As the touchdown was replayed at full speed, and therefore indistinguishable from live action, play-by-play man Lindsey Nelson declared, "This is not live! Ladies and gentlemen, Army did not score again." According to Verna, the first replay tape, which has since been lost, was recorded over a tape that included episodes of I Love Lucy. Verna went on to a distinguished career in television and detailed the invention of instant replay in a 2008 book.

Early Spread and Opinions of Instant Replay

Instant replay slowly became more ubiquitous. In 1965, the New York Times reported on a new feature of baseball broadcasts on ABC, which was the first network to use slow motion replay. "At least one station plans to introduce 'instant replay' and also a 'stop motion' or 'freeze' technique that could prove whether a base umpire's call on a runner was in reality right or wrong," Val Adams wrote. "The day of reckoning for umpires may be near." Former baseball slugger Ralph Kiner, a commentator for the Mets, had a different opinion. "I never saw the camera yet that could countermand an umpire, considering that the camera angle is just as prone to error as anything else," Kiner said. "In fact, video tapes seem to show how few mistakes umpires make."

A Costly and Useful Innovation

Instant replay, especially in the early days, was an expensive production. In 1966, the Pacific 8 college football conference voted to outlaw the television device that enabled football coaches to view instant replays on the field. Most of the schools that voted against the device, which provided a competitive advantage, did so because of the cost associated with purchasing one. There were other instances when coaches wondered when instant replay would be adopted to improve the game. One such example came in 1966, when Florida defeated rival Florida State in a game that featured a controversial finish. Officials ruled that FSU receiver Lane Fenner was out of bounds when he caught what would have been the winning touchdown. "I know it's a judgment call and there is nothing I can do about it," Florida State head coach Bill Peterson said. "But with all the electronic devices we have in football, why don't we have videotape or something like it to help officials?" Dave Nelson, a secretary for the NCAA, replied, "It is not true that pictures don't lie." College football wouldn't adopt a form of instant replay to determine calls until 2004.

In-Stadium Discretion

While leagues didn’t initially adopt instant replay for use by umpires and officials, teams took advantage of the technology to improve the in-stadium experience for fans. In April 1977, the four-man umpiring crew of a game between the Braves and Astros in Atlanta left the field in protest of the scoreboard operator’s decision to show a controversial replay. Predictably, the crowd began to boo the umpires after the replay revealed that they had made an incorrect call. The umpires received word from Braves management that close plays would not be replayed in the future before returning to the field. In fact, the Braves installed a former major league umpire in the press box to decide whether a specific play was too controversial to show.

One year earlier, the New York Yankees were fined $1,000 and reprimanded by the league after using their instant replay scoreboard to “produce fan reaction against the umpires.” A Yankees team spokesman responded in The New York Times, “We would like to point out that we have only the fans in mind when we use our scoreboard for instant replays. The board cost us $30 million and we see no reason why fans at the ballgame should see any less than the fans at home.” Today, most leagues have policies about what replays can be shown in stadiums and arenas. In the NFL, only the broadcast feed is shown on video screens and it must not be shown after the referee makes his call. You’re unlikely to see a replay of a close play on the scoreboard at a baseball game, especially a questionable ball or strike call.

The NFL’s Trial Run and Instant Replay Adoption

The NFL implemented a trial run of instant replay during seven preseason games in 1978. “We’ll do a dry run on the replay on officiating decisions,” Commissioner Pete Rozelle told reporters. “We’re not going to implement anything, but it will be part of a study.” In 1986, the NFL approved replay for use in regular season games. A game official in the press box reviewed plays on the same feed that viewers at home saw and had the authority to reverse any call that was “totally conclusive.” The league mandated that any replay decision be made within 15 to 20 seconds so as not to disrupt the flow of the game. “It will be expensive,” Tex Schramm said at the time. “But money doesn’t make any difference to this league.”

Communication between the replay official and the on-field was initially a problem. During a Monday night game early in the season, the on-field officials nullified a Denver Broncos touchdown because of what they ruled was an illegal forward lateral. The official in the replay booth reviewed the play and determined that the call was wrong, but by that point the Broncos had already run another play. Toward the end of the season, The New York Times and CBS Sports conducted a poll about the system. Sixty-six percent of fans thought it improved the game; 20 percent thought it made the game worse. Coaches and owners voted to drop replay in 1992, complaining that it slowed the pace of games, but voted 28-3 in favor of reinstating it as a challenged-based system before the 1999 season.

Baseball Resists

Perhaps in the interest of preserving the heritage of America’s national pastime, baseball has been the most hesitant of the major sports to adopt replay. In 1988, MLB Commissioner Peter Ueberroth declared, "There will not be instant replay of any sort. We're just not going to do it. The umpires making split-second decisions is part of the flavor of the game. We don't want to lose that flavor. You can make a dish so bland that it's not worth sitting down at the table." Ueberroth’s announcement came one week after an umpire used a scoreboard replay to reverse one of his calls.

In 2008, the league instituted replay of disputed home run calls. This season, Armando Galarraga’s imperfect perfect game, in which first base umpire Jim Joyce botched a call on what should have been the final out of the game, brought baseball’s replay debate front and center once again. The Little League World Series began using instant replay in 2008 and switched to a challenge-based system this year. Each manager receives one challenge per game, and if the umpire's call is overturned, the coach retains his or her challenge.

Replay Rules and Systems in Other Sports

Here is a sampling of how replay is currently used in other sports:

National Hockey League: The NHL began using instant replay in 1991. In 2003, the league adopted a replay system that took the responsibility of making controversial calls out of the hands of an in-stadium replay official and bestowed it upon NHL staffers watching every game live from a Toronto office often referred to as the “War Room.” In addition to reviewing disputed goals, the office staffers, who have access to every television broadcast of every game, watch for illegal hits that may warrant a suspension or fine.

National Basketball Association: The NBA began using instant replay to review last-second shots after the 2001-2002 season. Since then, instant replay has been expanded to include reviews of flagrant fouls and to determine if a field goal attempt was a 2-pointer or a 3-pointer. Replay is also used to review possible 24-second shot clock violations and to determine which player last touched the ball before it went out of bounds during the last 2 minutes of regulation and overtime.

Tennis: The Hawk-Eye computer system, which processes the trajectory of a ball using several video cameras and displays a computer rendering of the ball’s path, has been used to review disputed tennis calls since 2006. In 2008, the sport’s various organizing bodies developed a uniform system of rules for utilizing the technology and decided a player would be allowed three unsuccessful challenges per set. Cricket uses the Hawk-Eye system to help determine difficult calls as well.

Soccer: Instant replay isn’t used, though some fans would like to see that change, especially after some of the disputed calls at this year’s World Cup.

Instant Replay Outside of Sports

In 1967, the Federal Highway Administration announced that it would repurpose Verna’s innovation and use video and replay capabilities to monitor busy intersections. According to an article in The New York Times, the FHWA developed a video device that would be triggered by the sound of a crash at a busy intersection. The resulting signal would preserve the video from 20 seconds before impact, which aided in the investigation and analysis of collisions. Today, the U.S. military uses the same technology the NFL uses for instant replay to analyze thousands of hours of video from Afghanistan and Iraq.

15 Uplifting Facts About the Wright Brothers

Before they built the world’s first powered, heavier-than-air, and controllable aircraft, Wilbur and Orville Wright were two ordinary brothers from the Midwest who possessed nothing more than natural talent, ambition, and imagination. In honor of National Aviation Day, here are 15 uplifting facts about the siblings who made human flight possible.

1. A TOY PIQUED THEIR PASSION.

From an early age, Wilbur and Orville Wright were fascinated by flight. They attribute their interest in aviation to a small helicopter toy their father brought back from his travels in France. Fashioned from a stick, two propellers, and rubber bands, the toy was crudely made. Nevertheless, it galvanized their quest to someday make their very own flying machine.

2. THEIR GENIUS WAS GENETIC.

While they were inspired by their father’s toy, the Wright brothers inherited their mechanical savvy from their mother, Susan Koerner Wright. She could reportedly make anything, be it a sled or another toy, by hand.

3. THEY WERE PROUD MIDWESTERNERS.

The Wright brothers spent their formative years in Dayton, Ohio. Later in life, Wilbur said his advice for those seeking success would be to “pick out a good father and mother, and begin life in Ohio.”

4. THEY NEVER GRADUATED HIGH SCHOOL.

While the Wright brothers were undoubtedly bright, neither of them ever earned his high school diploma. Wilbur became reclusive after suffering a bad hockey injury, and Orville dropped out of school.

5. THEY ONCE PUBLISHED A NEWSPAPER.

Before they were inventors, the Wright brothers were newspaper publishers. When he was 15 years old, Orville launched his own print shop from behind his house and he and Wilber began publishing The West Side News, a small-town neighborhood paper. It eventually became profitable, and Orville moved the fledgling publication to a rented space downtown. In due time, Orville and Wilbur ceased producing The West Side News—which they’d renamed The Evening Item—to focus on other projects.

6. THEY MADE A FORAY INTO THE BICYCLE BUSINESS.

One of these projects was a bike store called the Wright Cycle Company, where Wilbur and Orville fixed clients’ bicycles and sold their own designs. The fledgling business grew into a profitable enterprise, which eventually helped the Wright brothers fund their flight designs.

7. THEY WERE AUTODIDACTS.

The Wright brothers’ lifelong interest in flight peaked after they witnessed a successive series of aeronautical milestones: the gliding flights of German aviator Otto Lilienthal, the flying of an unmanned steam-powered fixed-wing model aircraft by Smithsonian Institution Secretary Samuel Langley, and the glider test flights of Chicago engineer Octave Chanute. By 1899, Wilbur sat down and wrote to the Smithsonian, asking them to send him literature on aeronatics. He was convinced, he wrote, “that human flight is possible and practical.” Once he received the books, he and Orville began studying the science of flight.

8. THEY CHOSE TO FLY IN KITTY HAWK BECAUSE IT PROVIDED WIND, SOFT SAND, AND PRIVACY.

The Wright brothers began building prototypes and eventually traveled to Kitty Hawk, North Carolina, in 1902 to test a full-size, two-winged glider with a moveable rudder. They chose this location thanks in part to their correspondence with Octave Chanute, who advised them in a letter to select a windy place with soft grounds. It was also private, which allowed them to launch their aircrafts with little public interference.

9. THEY ACHIEVED FOUR SUCCESSFUL FLIGHTS WITH THEIR FIRST AIRPLANE DESIGN.

The Wright brothers started testing various wing designs and spent the next few years perfecting their evolving vision for a heavier-than-air flying machine. In the winter of 1903, they returned to Kitty Hawk with their final model, the 1903 Wright Flyer. On December 17, they finally achieved a milestone: four brief flights, one of which lasted for 59 seconds and reached 852 feet.

10. THE 1903 WRIGHT FLYER NEVER TOOK TO THE SKIES AGAIN…

Before the brothers could embark on their final flight, a heavy wind caused the plane to flip several times. Because of the resulting damage, it never flew again. It eventually found a permanent home in the Smithsonian’s Air & Space Museum—even though Orville originally refused to donate it to the institution because it claimed that Smithsonian Secretary Samuel P. Langley’s own aircraft experiment was the first machine capable of sustained free flight.

11. …BUT A PIECE OF IT DID GO TO THE MOON.

An astronaut paid homage to the Wright brothers by carrying both a swatch of fabric from the 1903 Flyer’s left wing and a piece of its wooden propeller inside his spacesuit.

12. THE PRESS INITIALLY IGNORED THE KITTY HAWK FLIGHTS.

Despite their monumental achievement, the Dayton Journal didn’t think the Wright brothers’ short flights were important enough to cover. The Virginia Pilot ended up catching wind of the story, however, and they printed an error-ridden account that was picked up by several other papers. Eventually, the Dayton Journal wrote up an official—and accurate—story.

13. THE BROTHERS SHARED A CLOSE BOND...

Although the Wright brothers weren’t twins, they certainly lived like they were. They worked side by side six days a week, and shared the same residence, meals, and bank account. They also enjoyed mutual interests, like music and cooking. Neither brother ever married, either. Orville said it was Wilbur’s job, as the older sibling, to get hitched first. Meanwhile, Wilbur said he “had no time for a wife.” In any case, the two became successful businessmen, scoring aviation contracts both domestically and abroad.

14. …BUT WERE OPPOSITES IN MANY WAYS.

Although they were much alike, each Wright brother was his own person. As the older brother, Wilbur was more serious and taciturn. He possessed a phenomenal memory, and was generally consumed by his thoughts. Meanwhile, Orville was positive, upbeat, and talkative, although very bashful in public. While Wilbur spearheaded the brothers’ business endeavors, they wouldn’t have been possible without Orville’s mechanical—and entrepreneurial—savvy.

15. OHIO AND NORTH CAROLINA FIGHT OVER THEIR LEGACY.

Since the Wright brothers split their experiments between Ohio and North Carolina, both states claim their accomplishments as their own. Ohio calls itself the "Birthplace of Aviation,” although the nickname also stems from the fact that two famed astronauts hail from there as well. Meanwhile, North Carolina’s license plates are emblazoned with the words “First In Flight.”

12 Facts About Elizabeth Cady Stanton

Elizabeth Cady Stanton (1815-1902) was never able to cast a vote legally, though she helped secure that right for women across America. As the philosopher of the women’s rights movement in 19th-century America, she expressed what she felt regardless of what others might think. Read on for more facts about one of the most important women in history.

1. HER FATHER WISHED SHE HAD BEEN A BOY.

Cady Stanton’s father, Daniel Cady, served in Congress and the New York State Assembly, and was a New York Supreme Court judge. He and his wife Margaret had 11 children; five daughters, including Elizabeth, and one son would survive to adulthood. When her brother Eleazar died at age 20, Elizabeth’s father allegedly said to her, “Oh my daughter, I wish you were a boy!”

That may have been her father’s way of lamenting the hardships she would suffer as a woman, but Elizabeth responded by throwing herself into studying Greek, chess, and horse riding, vowing “to make her father happy by being all a son could have been,” Lori D. Ginzberg writes in Elizabeth Cady Stanton: An American Life. Daniel Cady did encourage his bright and self-confident daughter when she was upset that laws could not help one of his female clients: “When you are grown up, and able to prepare a speech, you must go down to Albany and talk to the legislators,” he told her. “If you can persuade them to pass new laws, the old ones will be a dead letter.”

2. A PREACHER ACTUALLY SCARED THE BEJESUS OUT OF HER.

Even as a young person, Elizabeth bristled against her family’s Presbyterian beliefs. In 1831, as a required part of her lessons at the Troy Female Seminary, she attended a revival at which noted evangelist Charles Grandison Finney spoke. She found his ideas about sin so alarming that she had to take time off from school to recover. Ultimately, she rejected organized Christianity’s dependence on fear, and later came to view religion as at odds with her work in the feminist movement.

3. SHE SPENT HER HONEYMOON AT AN ANTI-SLAVERY CONVENTION.

In 1840, Elizabeth married Henry Stanton, a prominent abolitionist who was active in the New York Anti-Slavery Society. After the wedding, the new couple headed to the World Anti-Slavery Convention in London, where Henry was a delegate and Elizabeth was forced with other female attendees into the back of the lecture hall [PDF]. There she met feminist Lucretia Mott, who shared her support for women’s and African Americans' rights.

4. CADY STANTON ATTENDED AN EPIC TEA PARTY …

When you think of an important tea party, the Boston event probably springs to mind—but there was at least one other tea-related confab that was just as historic.

On July 9, 1848, Cady Stanton and three other women—Lucretia Mott, her sister Martha Wright, and Mary Ann McClintock—were invited to the Waterloo, New York home of Jane Hunt, a wealthy Quaker dedicated to social reform. During the gathering, they discussed how women weren’t allowed to vote or own property and why the Quaker religion avoided getting involved with women’s rights and the anti-slavery movement. The decision to create an organized meeting to advocate women’s equality was decided right then and there, though who came up with the idea is not known.

5. ... WHICH LED TO THE FIRST WOMEN’S RIGHTS CONVENTION IN AMERICA.

Cady Stanton, Mott, and their colleagues announced “a Convention to discuss the social, civil, and religious condition and rights of woman.” Ten days after the tea party, more than 300 people attended the event (also known as the Seneca Falls convention). The first day, July 19, was planned as an all-women discussion, and July 20 was open to the public.

Stanton wrote and read a “Declaration of Sentiments and Grievances” for the occasion, a discourse based on the Declaration of Independence describing the oppression of women and the rights to which they were entitled. It began with these famous lines: “We hold these truths to be self-evident, that all men and women are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are life, liberty, and the pursuit of happiness.” (The Declaration of Independence had almost identical wording except for the “and women” part.) Sixty-eight women and 32 men signed the declaration. Seneca Falls launched annual conventions to advocate women’s rights, and was the start of the long battle that eventually earned women the right to vote.

6. CADY STANTON AND SUSAN B. ANTHONY WERE BFFS.

Cady Stanton met Susan B. Anthony in 1851 and they quickly became an unstoppable pair. In their shared goal of achieving women’s equality, Anthony handled the campaigning and speeches, while Cady Stanton did the lion’s share of the writing from her home in Seneca Falls. While Anthony objected to Cady Stanton allowing her role as a mother to interfere with her reform work, she also helped her take care of the seven Stanton children. Cady Stanton said of Anthony:

“In the division of labor we exactly complemented each other. In writing we did better work than either could alone. While she is slow and analytical in composition, I am rapid and synthetic. I am the better writer, she the better critic. She supplies the facts and statistics, I the philosophy and rhetoric, and, together, we have made arguments that have stood unshaken through the storms of long years—arguments that no one has answered. Our speeches may be considered the united product of our two brains."

Together, they formed the anti-slavery Women’s Loyal National League and published the first three of six volumes of History of Woman Suffrage.

7. SHE OPPOSED THE 15th AMENDMENT.

Cady Stanton and Anthony also founded the National Woman Suffrage Association in 1869 in response to the proposed 15th Amendment. According to Ginzberg, feminists faced a choice after the Civil War, when Congress debated suffrage for emancipated slaves. “There was a battle among abolitionists—of which Stanton counted herself—between having a 15th Amendment that gave black men the vote or holding out for a suffrage amendment that granted the vote to all adult Americans,” Ginzberg told NPR. “Stanton and her friend Susan B. Anthony stood on what they claimed was the highest moral ground by demanding universal human rights for all and—historians have argued about this ever since—not being willing to sacrifice women's rights for the politically expedient challenge of gaining rights for black men.” The 15th Amendment, giving men the right to vote regardless of “race, color, or previous condition of servitude,” was ratified in 1870. Women did not end up achieving the franchise until 1920.

8. SHE RAN FOR CONGRESS.

Women could run for public office even though they couldn’t vote, a situation that Cady Stanton sought to challenge. She ran for the U.S. House of Representatives—the first woman to do so—as an independent representing New York in 1866. She knew that she was treading new ground when she announced she was running. “I have no political antecedents to recommend me to your support, but my creed is free speech, free press, free men, and free trade—the cardinal points of democracy,” she explained in a letter. She received only 24 votes of the 12,000 cast, perhaps a reflection of the fact that no women could vote—but her audacious campaign likely inspired others. Six years later Victoria Woodhull became the first female candidate for president. It wasn’t until 1916 that a woman, Rep. Jeannette Rankin of Montana, was elected to Congress.

9. SHE WROTE A BESTSELLING CRITIQUE OF CHRISTIANITY.

Her 1895 book The Woman’s Bible, which criticized the ways religion portrayed women as less than men, drove a wedge between Stanton and the women’s movement. Cady Stanton argued that the Bible taught “the subjection and degradation of woman” and that equality demanded a revision of its lessons. Anthony felt it was more important to welcome people of all religious beliefs into the fight for suffrage. Thanks to the controversy, the book became a bestseller.

10. SHE BELIEVED BIKES WOULD LIBERATE WOMEN.

As the 1970s feminist slogan goes, “a woman needs a man like a fish needs a bicycle.” In Cady Stanton’s day, a bike made it so that a woman wouldn’t need a man, at least when it came to transportation. Biking had become popular by the 1890s, and was strongly associated with the modern woman of the latter part of the 19th century, liberated from stuffy social and marital expectations. At 80, Stanton told The American Wheelman magazine that “the bicycle will inspire women with more courage, self-respect [and] self-reliance,” eventually leading to women’s suffrage. Both she and Susan B. Anthony have been credited with saying “woman is riding to suffrage on the bicycle.” They could see beyond the convenience of getting from point A to point B: Bikes symbolized a new freedom for women.

11. SHE TRIED TO DONATE HER BRAIN TO SCIENCE.

Cady Stanton died in 1902, just before turning 87. Susan B. Anthony was heartsick. “I am too crushed to speak,” she told The New York Times’s obituary writer.

But Cady Stanton had tried to ensure that she would still help women’s causes after her own death. Her friend Helen Gardener, a fellow suffragist, had convinced her to donate her brain to Cornell University so scientists would have an eminent female brain to compare with those of eminent men. Stanton had told her family of her plan, and Gardener announced her wishes publicly. Gardener said Cady Stanton “felt that a brain like hers would be useful for all time in the record it would give the world, for the first time—the scientific record of a thinker among women,” Kimberly A. Hamlin writes in From Eve to Evolution: Darwin, Science, and Women’s Rights in Gilded Age America. Cady Stanton’s family, however, refused to believe she had agreed to the plan, and the brain was buried with the rest of her in the Bronx’s Woodlawn Cemetery.

12. SHE WILL APPEAR ON THE $10 BILL IN 2020.

The 19th Amendment, which finally gave women the right to vote, celebrates its centennial in 2020. To commemorate the anniversary, a new $10 bill will be issued with Elizabeth Cady Stanton, Lucretia Mott, Sojourner Truth, Susan B. Anthony, and Alice Paul on the back—the first time in more than 100 years that a female portrait has been featured on paper money. (Alexander Hamilton will remain on the front.) You can also expect to see Cady Stanton and Anthony memorialized in a bronze statue in New York City’s Central Park that will be known as the Elizabeth Cady Stanton and Susan B. Anthony Woman Suffrage Movement Monument. Amazingly, the suffrage pioneers are the first two women to be honored with statues in Central Park, and only the fourth and fifth American women represented by public statues in any NYC park.
