Scoreboard buzzers have been part of indoor arena sports for decades, wired to the game clock in basketball, hockey and other timed sports to announce the end of periods and shot clock violations. The short, abrasive tone was designed to be heard over crowd cheering and by officials across the court. Online, creators borrowed that same finality for quizzes, challenges and reaction edits, where the buzzer now works as a universal shorthand for time expired or an attempt rejected, even when no sport is shown on screen at all.
