Emoticon in the context of Scott Fahlman

Punctuation marks are marks indicating how a piece of written text should be read (silently or aloud) and, consequently, understood. The oldest known examples of punctuation marks were found in the Mesha Stele from the 9th century BC, consisting of points between the words and horizontal strokes between sections. The alphabet-based writing began with no spaces, no capitalization, no vowels (see abjad), and with only a few punctuation marks, as it was mostly aimed at recording business transactions. Only with the Greek playwrights (such as Euripides and Aristophanes) did the ends of sentences begin to be marked to help actors know when to make a pause during performances. Punctuation includes space between words and both obsolete and modern signs.

By the 19th century, grammarians explained the difference between the punctuation marks by means of a hierarchy that ascribed different weight to them. Six marks, proposed in 1966 by the French author Hervé Bazin, could be seen as predecessors of emoticons and emojis.

A smiley, also known as a smiley face, is a basic ideogram representing a smiling face. Since the 1950s, it has become part of popular culture worldwide, used either as a standalone ideogram or as a form of communication, such as emoticons. The smiley began as two dots and a line representing eyes and a mouth. More elaborate designs emerged in the 1950s, featuring noses, eyebrows, and outlines. New York radio station WMCA used a yellow and black design for its "Good Guys!" campaign in the early 1960s. More yellow-and-black designs appeared in the 1960s and 1970s, including works by Harvey Ross Ball in 1963, and Franklin Loufrani in 1971. The Smiley Company, founded by Franklin Loufrani, claims to hold the rights to a version of the smiley face in over 100 countries. It has become one of the top 100 licensing companies globally.

There was a "smile face" fad in 1971 in the United States. The Associated Press (AP) ran a wirephoto showing Joy P. Young and Harvey Ball holding the design of the smiley and reported on September 11, 1971, that "two affiliated insurance companies" claimed credit for the symbol and Harvey Ball designed it; Bernard and Murray Spain claimed credit for introducing it to the market. This referred to the Worcester Mutual Fire Insurance Company of America and the Guarantee Mutual Assurance Company of America, whose 1963 "Smile Power" campaign first distributed smiley buttons to employees. In October 1971, Loufrani trademarked his design in France while working as a journalist for the French newspaper France-Soir.Today, the smiley face has evolved from an ideogram into a template for communication and use in written language. The internet smiley originated with Scott Fahlman in the 1980s, when he first theorized that ASCII characters could be used to create faces and convey emotions in text. Since then, Fahlman's designs have become digital pictograms known as emoticons. They are loosely based on the ideograms designed in the 1960s and 1970s, continuing with the yellow and black design.

Kaomoji are Japanese emoticons that use combinations of text characters to represent facial expressions and emotions. They first appeared in Japan during the 1980s, offering a distinctive way to convey tone and mood in digital communication. Common examples include:

• (^ω^) – expresses happiness or excitement
• ( ͡o╭╮ ͡o) – conveys sadness or disappointment

Kaomoji developed independently around the same time that sideways emoticons (or smileys) began appearing in the United States, such as:
