Nancy Drew's popularity continues unabated: in 2002, the first Nancy Drew book published, "The Secret of the Old Clock", alone sold 150,000 copies, good enough for top-50 ranking in children's books, and other books in the series sold over 100,000 copies each. Sales of the hardcover volumes of the original Nancy Drew series alone has surpassed sales of Agatha Christie titles, and newer titles in the Girl Detective series have reached "The New York Times" bestseller lists. "Entertainment Weekly" ranked her seventeenth on its list of "The Top 20 Heroes" ahead of Batman, explaining that Drew is the "first female hero embraced by most little girls… lives in an endless summer of never-ending adventures and unlimited potential." The magazine goes on to cite "Scooby-Doo"s Velma Dinkley as well as Veronica Mars as Nancy Drew's "copycat descendants".
