Moe (萌え, Japanese pronunciation: [mo.e] ⓘ), sometimes romanized as moé or moe’ in English, is a Japanese word that refers to feelings of strong affection mainly towards characters in anime, manga, video games, and other media directed at the otaku market. Moe, however, has also gained usage to refer to feelings of affection towards any subject.

Moe is related to neoteny and the feeling of “cuteness” a character can evoke. The word moe originated in the late 1980s and early 1990s in Japan and is of uncertain origin, although there are several theories on how it came into use. Moe characters have expanded through Japanese media, and the concept has been commercialised. Contests, both online and in the real world, exist for moe-styled things, including one run by one of the Japanese game rating boards.

Moe characters have expanded within the Japanese media market. In 2003, the market for moe media such as printed media, video, and games was worth 88 billion yen; roughly one-third of the estimated 290 billion yen otaku market in Japan.[16] In 2009, Brad Rice, editor-in-chief of Japanator, said that “moe has literally become an economic force” saying that more products use some element of moe in order to sell better. Rice also goes on to say that moe is used to get anime and manga works out to “hardcore fans who buy excessive amounts of items related to the character of their desire.”[17] Source: Wikipedia
