Emoji have become a global trend in communication through mobile technologies. They originated in 1999 in Japan as a way to express more information in text messages through pictures. Emoji allow people to convey tone and emotion concisely. Research found that people most commonly use emoji like smiley faces, laughing crying faces, and kiss faces in texts to convey moods and add humor without risk of being misinterpreted. While emoji began as pictures in texts, they are now used across advertising and other media to understand consumer sentiment. Some argue emoji risk commodifying emotions, but most research participants said emoji help express individualism even while participating in shared communication trends.
