Quick Summary

A laugh track is recorded laughter added to television programs to simulate an audience's reaction. This practice, known as "sweetening," originated in the 1940s to enhance the comedic effect and create a more engaging viewing experience for at-home audiences, mimicking a communal, theater-like atmosphere. Sound engineer Charles Douglass developed a machine in 1953 to produce this artificial laughter. Despite its artificial nature, laugh tracks have been found to induce positive audience responses, often correlating with higher ratings and increased audience retention.12
