Barnes & Noble Inc said that sales of digital books made through its website now exceed those of traditional books that it sells online. The world's largest bookseller also today announced that with millions of NOOK eReading devices sold, the line has become the company's biggest bestseller ever in its nearly 40-year history. The new NOOKcolor Reader's Tablet, introduced just eight weeks before Christmas, is the company's number one selling gift of the holiday season.

Barnes & Noble also announced that it now sells more digital books than its large and growing physical book business on BN.com, the world's second largest online bookstore.

Demand for the NOOKcolor remained high following the product's introduction in late October through the holidays, the company said. The company also experienced robust sales for its line of NOOK 3G and Wi-Fi devices, which feature an E-Ink display and a color touchscreen for navigation.

The company also reported record holiday sales from its comprehensive two-million-title catalog, including nearly one million NOOKbooks purchased and downloaded on Christmas Day alone. Through Barnes & Noble's eReading offerings, users can buy and read their NOOKbooks on NOOKcolor, NOOK 3G, Wi-Fi, and using NOOK apps on popular devices including iPad, iPhone, Android smartphones and more.

It features a 7-inch VividView Color Touchscreen. NOOKcolor is available at your local Barnes & Noble store and at www.NOOKcolor.com, as well as Best Buy, Walmart and Books-A-Million stores.
