When the fifth Harry Potter book is released in June, it will, of course, be the biggest literary event of the year in the English-speaking world. But how big, exactly, have Harry and his Hogwarts buddies become? “Worldwide, Amazon.com has received more than 875,000 orders for the book… The U.S. publisher of the Potter books, Scholastic, is planning a press run of 8.5 million.” The cross-promotion is rampant, as well. The two big-budget movies “are both now out on video. Harry Potter clothing, backpacks, lunchboxes and video games crowd store shelves. There’s a line of Harry Potter Lego that lets kids build their own Hogwarts Castle. Harry Potter is never out of the public eye.”
