Human: What is the history of the emoji? Assistant: 
The emoji was first introduced in Japan in the late 1980s. It was originally called a "kana-moji" (Japanese: カナ文字, kan'a-moji) and was designed to be used with mobile phones that could not display images. The original design consisted of a small number of characters, including a smiling face, a crying face, a surprised face, a laughing face, a winking face, and a frowning face. In the early 1990s, the Unicode Consortium adopted this set as the first standard for emoji.
