Brown's 'Symbol' sells 1M copies in 1 day

NEW YORK, Sept. 16 (UPI) -- Dan Brown's eagerly awaited novel "The Lost Symbol" sold 1 million copies the day it was released in the United States, England and Canada, its publisher said.

Brown's previous books "The Da Vinci Code" and "Angels & Demons" were blockbusters that were adapted as hit movies.

Knopf Doubleday Publishing Group told The New York Times it is printing another 600,000 copies of "Symbol" after more than 1 million hardcover and e-book versions were sold Tuesday.

The publisher's first run of the thriller was 5 million copies.
