ABC News reports on the growing popularity of manga among girls.
Since when have women become comic fans? Since the explosion of Japanese-style cartoons, known as "manga."
This same style of cartooning is known as "anime," when the pictures are moving, in video or film.
"There was an audience here waiting, girls that watched 'Sailor Moon' and loved it," said Svetlana Chmakova, an artist who draws Japanese-style manga comics, for Cosmo Girl Magazine and publisher TokyoPop.
"Sailor Moon" is one of the most famous Japanese television cartoons in the world.
It began running on American television in the mid-1990s, and a film version was released by Disney, the parent company of ABC, in 2000.
Since then, manga has exploded in popularity here in the United States, and most of the fans are female.
Calvin Reed of Publisher's Weekly said: "What has been driving the sales of manga in this country is 'shojo' manga, aimed at girls. Comics aimed at a girl's sensibility are great at creating a comics market in the bookstore market."
Here is another difference.
Girls aren't buying their comics in comic book shops; they're shopping at bookstores, and bookstores are responding by stocking more and more of them.
North American manga sales have tripled in the last three years, from $50 million in 2002 to $155 million in 2005.
Sales of graphic novels - comics in book form that include manga - have tripled in the last five years.
The popularity of manga is only going to grow, in our opinion. The animated cartoons brought in an entirely new audience of readers, and those readers are continuing to read the stories well into their twenties and thirties.
