The History of the Football Scoreboard and the Stats Sheet
How football learned to show the score and keep the numbers: from hand-kept tallies and flip boards to video screens, official statisticians and player-tracking chips.
Ask someone what the score of a football game is and they will glance at a screen. Ask who gained the most yards, how many times the quarterback was sacked, or how long the final drive took, and the answer is on a stat sheet that was assembled while the game was still being played. We rarely think about either one. The score and the numbers simply appear.
They did not always. The first football games were played with little more than a referee, a watch and a notebook, and a spectator who wanted to know what had happened often had to wait for the next morning's newspaper. This article follows the long road from that world to the scoreboards and data feeds of today, and explains along the way why some statistics are "official" while others are not.
Keeping score by hand
In the early decades of the sport, the score was kept by the officials and by a small number of people on the sidelines. Crowds learned the score the way crowds always have: by watching, by asking the person next to them, and by listening to an announcement. Stadiums of the time sometimes had a blackboard, a painted board with numbers that a worker would update, or a simple announcement over a megaphone. Time was the most difficult piece of information to share, because the official watch belonged to the referee or a timekeeper, and the crowd could not see it.
This shaped how the game was played. When the end of a half came, the players, coaches and fans might all be uncertain exactly how much time was left. The timekeeper's decision was final, and the crowd learned the clock only when the official signaled the end of the period. The idea that everyone in the stadium should see the same running clock is a modern invention.
The mechanical scoreboard
As stadiums grew, so did the need to show information to thousands of people at once. Scoreboards began to appear as permanent fixtures, and early versions were mechanical or electromechanical, with numbers that were flipped by hand or turned by motors. A person inside the structure updated the figures as the game progressed.
A football scoreboard has to show more than a baseball or basketball board does, because football has unusual information to convey. A useful board tells the viewer:
- The score for each team.
- The quarter and the time remaining.
- The down and the distance to go for a first down.
- The team in possession.
- The timeouts each team has left.
- In many venues, the spot of the ball.
Each addition arrived as the technology made it practical. The down-and-distance display is a good example. It exists because the game has a specific unit of progress, the series of downs, and fans need to know where they stand within it. The chain crew on the field still marks the same information with a physical chain and a down marker, a system we describe in our article on the chain gang, and the scoreboard and the chains tell the same story in two different ways.
Who runs the clock
An important question about any scoreboard is whether its clock is the official one. For much of football's history, the game's official time was kept by an official on the field, and the stadium clock was a courtesy. As clocks became more reliable, leagues and governing bodies adopted the scoreboard clock as the main reference for most purposes, with officials retaining authority to correct it when it is wrong. The details differ by level and by year. In some high school games, the scoreboard clock is the official time. In others, a field official keeps the official clock, and the scoreboard is a display. If you are watching a small-school game and the clock seems to disagree with the referee, that is likely the explanation.
From light bulbs to video screens
The next stage was electrification. Light-bulb boards could show numbers, flashing messages and simple graphics, and they let stadiums display more than a score. A famous example in the sport is the huge scoreboard installed when the Houston Astrodome opened in the mid-1960s, which became known for its animated displays and fireworks-style effects. It signaled that a scoreboard could be entertainment as well as information.
Over the following decades the technology moved from bulbs to light-emitting diodes and then to full-color video screens. Companies that specialized in scoreboards grew into a business of their own, serving high schools, colleges and professional teams. The large video boards that you see in modern stadiums descend from a development in the mid-1980s, when Sony introduced its first large outdoor video display at a world exposition in Japan under the trade name Jumbotron. The name has since become a general term for a big stadium screen.
Instant replay
A video board raises a question that did not exist for a light-bulb board: should it show replays? Instant replay itself was first used on television. A director named Tony Verna is credited with the first use of instant replay in a live broadcast, in a December 1963 telecast of the Army-Navy game. It was a technical experiment, and viewers were so surprised that the announcers had to explain to them that they were watching a replay of what had just happened.
Stadium video boards raised the stakes for officiating. If a replay shows a call to have been wrong, the crowd sees it. Leagues have adopted policies on what stadium screens may display during a game, and they vary by level. How review works today is a separate subject, and the policy for high school stadiums is set by local associations and schools.
The play clock
The scoreboard also hosts the play clock, which counts down the time the offense has to snap the ball. The play clock exists because teams used to be able to stall, and the rules had to specify a limit. It is shown in the stadium so that the players, officials and fans can see the same countdown. The number of seconds varies by level and situation, and failing to snap in time is a delay-of-game penalty.
How football statistics began
Scoreboards show the score; statistics describe how it happened. Football has always had some form of record keeping, but the quality and consistency of the records have varied widely.
In the early years of the professional game, there were no standard rules for what to count, and the records were incomplete. Leagues relied on newspaper accounts, team records and the memory of the people who had been there. Rushing yards and passing yards were recorded, but the definitions were not uniform, and a number that appears in a record book may not be comparable to one from a later period. The NFL's official statistical record for individual players begins in the early 1930s. That is why historians can tell you the totals for a particular player in some seasons and only an estimate or an unknown for others.
The official statistician
A league that publishes records needs one body to decide what counts. The NFL relies on an official statistician, and that role has been filled by Elias Sports Bureau, a company with a long history in sports record keeping, for many decades. The statistician's job is to maintain a consistent record, apply the league's definitions, and rule on scoring decisions that are not obvious.
Scoring decisions are more complicated than they sound. Consider a play on which a receiver catches a short pass, takes a few steps, and loses the ball as he is hit. Is it a completion followed by a fumble, or an incomplete pass because he did not complete the catch? The answer depends on the definition of a catch, which has changed over the years. The scorer follows the officials' ruling, and the statistics follow the scorer.
Which numbers are official
One of the most common sources of confusion among fans is why some statistics seem to differ between sources. The reason is that not every number is equally official.
Sacks
Sacks are a good example. Defensive linemen and linebackers had been credited with quarterback sacks for years, but the NFL did not count sacks as an official statistic until 1982. That is why you may see a famous pass rusher from the 1960s or 1970s with sack totals that appear in books and on websites but not in the league's record book. Those totals were compiled later from film and team records, and they are unofficial. The leaders in a given era were real, but the record is not comparable to the official era that followed.
Tackles
Tackles are different. The NFL has never treated tackles and assists as official league statistics. They are recorded by the home team's statistical crew and can differ from stadium to stadium, which is why the numbers sometimes change when the league or the team revises them after review. A fan comparing two players' tackle totals should treat them as approximate. We discuss how statistics like this are read in our guide to the NFL box score.
Other categories
A number of figures are tallied by teams and reviewed by the league. Examples include time of possession, penalty yards and third-down efficiency. Many of them are simple counts, but the definitions can still lead to differences: does a penalty that gives a first down count as a conversion? Does a kneel-down count as a rushing attempt? Leagues publish guidelines, and statisticians apply them, but small differences between websites are common.
College and high school statistics
College football has its own system. The NCAA publishes statistical rules, and schools are expected to follow them in their records, which are kept by the school's sports information staff. For most FBS games, a team of student and professional statisticians works from the press box. The college game's definitions are close to the pro game's but not identical, and the NCAA's rules on how to credit particular plays differ in some cases. The way those numbers appear in the record books is explained in our guide to reading college stats.
High school statistics are the most variable. Some programs have a trained volunteer or student who keeps detailed numbers during the game. Others rely on a parent with a clipboard, and still others use a mobile app. The statistics are valuable to families and college recruiters, but they are rarely audited. If you are reading a stat line from a small school, treat it as a good estimate rather than an official record. A mistake in a box score is common, and coaches often correct it afterward.
Television changes what fans see
Television added another layer. In the 1990s, broadcasters began adding a permanent on-screen graphic that showed the score and clock, which is now standard. A major network introduced a permanent score box for its NFL coverage in 1994, and other networks followed. Viewers who once had to wait for an announcer to read the score could now see it throughout the game.
Another leap came in 1998, when a sports network used a computer-generated yellow line on the field to show the first-down marker during a live broadcast. The line looked like it was painted on the grass, and the technology required a system that could track camera positions and recognize the color of the field. Nothing about the rules changed, but the viewing experience at home shifted, and the fan on the sofa could now see the line to gain more clearly than some fans in the stadium.
These graphics are produced by the broadcaster, not the league, and they use the same data stream as the scoreboard.
Tracking chips and modern analytics
The latest chapter is tracking. In the mid-2010s the NFL began using small radio-frequency tags in player shoulder pads and in the ball to record the position of every player on the field many times a second. The data produces measures that no human statistician could capture, such as top speed, distance covered and the separation between a receiver and a defender at the moment of a catch. Teams and analysts use it to study routes and pass rushes, and some of it appears on broadcasts.
Tracking data has not replaced traditional statistics. Yards, completions and touchdowns remain the basis of the record book. But it has given teams and fans a way to measure aspects of the game that had previously been described only in words. For a look at how the newer metrics are used to judge performance, see our advanced stats primer.
Using this site's numbers
The scoreboard and stat sheet are now merged in digital form. Our scores page shows live results, the standings are computed from final scores, and the leaders page shows who is at the top of the statistical categories. Because different sources apply slightly different rules, you may see small differences between our numbers and those on a team website or in a league's official gamebook. The data sources page explains where our numbers come from.
The short version
- Early football had no standard scoreboard; the officials kept time, and the crowd often did not know the exact clock.
- Scoreboards moved from hand-turned boards to bulbs, to video screens, and added down, distance and the play clock.
- Instant replay was first used on television in 1963, and stadium video boards later forced leagues to decide what replays to show.
- The NFL's individual records start in the early 1930s, and sacks became an official statistic only in 1982.
- Tackles are recorded by home-team scorers and are not official league statistics, so totals can differ between sources.
- On-screen scoreboxes and the virtual first-down line came to television in the 1990s, and player-tracking chips arrived in the 2010s.
- High school stats vary the most; treat them as good estimates.
