 By the end of the 1970s, magazines devoted to the nascent genre started to appear, and in the 1990s the term "boys' love" or "BL" would be invented and would become the dominant term used for the genre in Japan.Although "yaoi" derives from girl's and women's manga and still targets the "shōjo" and "josei" demographics, it is currently considered a separate category.Keiko Takemiya's manga serial "Kaze to Ki no Uta", first published in 1976, was groundbreaking in its depictions of "openly sexual relationships" between men, spurring the development of the boys' love genre in "shōjo" manga, as well as the development of sexually explicit amateur comics.
