Tokyopop's Fruits Basket Vol. 16 has hit a new high for a manga (or any graphic novel for that matter) on the 'USA Today Best-Selling Books Top 150' for the week ending April 15th, with a #15 ranking.  The previous best performance by a manga, according to Anime News Network, was Naruto Volume 11, which hit #21 in September of last year. 

The #15 ranking for Fruits Basket illustrates a couple of trends we've been tracking over the past months.  One is that sales on the bestselling manga series are continuing to grow, with more people getting exposed to the most popular series every month by buying the first volumes of the series, which remain bestsellers.  A second is that manga continues to become more mainstream, and part of the fabric of American pop culture.
