A score bug is a digital on-screen graphic which is displayed in a broadcast of a sporting event, displaying the current score and other statistics.^[1] It is similar in function to a scoreboard, and is usually placed at either the top or lower third bottom of the television screen.

The concept of a persistent score bug for association football matches was devised by Sky Sports head David Hill, who was dissatisfied over having to wait to see what the score was after tuning into a match in-progress. The score bug was introduced when Sky launched its coverage of the then newly-formed English Premier League in August 1992. Hill's boss repeatedly demanded that the graphic be removed, describing it as the "stupidest thing [he] had ever seen". Hill defied the boss's demands and kept the graphic in place.^[2] ITV introduced a score bug at the start of the 1993–94 football season, and the BBC introduced a score bug towards the end of 1993.

The concept was introduced to the United States by ABC Sports and ESPN during coverage of the 1994 FIFA World Cup. Their justification for the graphic was to provide a location for a rotating series of sponsor logos, in order to allow matches to air without commercial interruption.^[2]

With the acquisition of rights to the National Football League (NFL) by BSkyB's American sibling Fox (a fellow venture of Rupert Murdoch), Hill became the first president of Fox Sports. Under Hill's leadership, Fox introduced a version of the score bug branded as the "Fox Box", which was part of its inaugural season of NFL coverage in 1994.^[2] Variety criticized it as an "annoying see-through clock and score graphic" and expressed concern for people "who actually watched the beginning of the game and would rather have their screen clear of graphics".^[3] Hill even received a death threat from an irate viewer, with a specific emphasis on him being a "foreigner",^[4] but the score bug soon became a ubiquitous feature for American football broadcasts, along with almost all American sports broadcasts in the years that followed.^[5][2]

Dick Ebersol of NBC Sports initially opposed the idea of a score bug, as he thought that fans would dislike seeing more graphics on the screen and would change the channel from blowout games if the score was constantly being displayed.^[6]

Since the 2010s, the on-air design and positioning of some score bugs have been influenced by the needs of Internet video (especially when viewing an event on devices with smaller screens), including bugs noticeably larger than prior iterations designed with television viewing in mind, and Fox having adopted a score bug positioned in the bottom-center of the screen for football (easing the ability for the bug to remain visible when highlights are cropped for square videos posted on social media).^[7][8][9]

Score bugs used in team sports typically include the names of both teams, an abbreviation of the team's name, and/or the team's logo; for individual sports, they include the names of individual competitors. In sports where a game clock or playing periods are used, those are generally also displayed as part of the score bug. Some broadcasts also include teams' win-loss records.^[10]

In addition to the above information, score bugs in some sports include additional information:

• In baseball, score bugs display the current inning, number of outs, the pitch clock if applicable, and a graphic displaying which bases are occupied; and usually include names of the current pitcher and batter, the pitcher's pitch count, and the number of balls and strikes accrued by the batter.^[11]
• In basketball, score bugs generally include the shot clock, the number of fouls accrued by each team, and whether a team is in the bonus.^[12][13]
• In American football, score bugs usually include the play clock and the down and distance of the current play;^[10] they also incorporate graphics indicating when a penalty flag has been thrown.^[14]
• In ice hockey, score bugs display when a penalty or power play is in effect, and often include the number of shots on goal accrued by each team.^[15]

Telecasts of automobile races and horse races often include a score bug with the current positions of participants, and the remaining distance or number of laps.^[16]
