Speech balloon

Speech balloons (also speech bubbles, dialogue balloons or word balloons) are a graphic convention used most commonly in comic books, comics and cartoons to allow words (and much less often, pictures) to be understood as representing the speech or thoughts of a given character in the comic. There is often a formal distinction between the balloon that indicates thoughts and the one that indicates words spoken aloud: the balloon that conveys subjective thoughts is often referred to as a thought bubble.

History

One of the earliest antecedents to the modern speech bubble were the "speech scrolls," wispy lines that connected first person speech to the mouths of the speakers in Mesoamerican art between 600 and 900 AD.

In Western graphic art, labels that reveal what a pictured figure is saying have appeared since at least the 13th century. These were in common European use by the early 16th century. Word balloons (also known as "banderoles") began appearing in 18th-century printed broadsides, and political cartoons from the American Revolution (including some published by Benjamin Franklin) often used them. With the development of the comics industry in the 20th century, the appearance of speech balloons has become increasingly standardized, though the formal conventions that have evolved in different cultures (USA as opposed to Japan, for example), can be quite distinct.
