It's a game of one-upmanship between Amazon and Barnes & Noble. Earlier this week, Amazon announced its third-generation Kindle is now the best selling product in the company's history, and not to be outdone, Barnes & Noble is saying the same thing about its Nook eBook reader.
"With millions of Nook eReading devices sold, the line has become [Barnes and Noble's] biggest bestseller ever in its nearly 40-year history," B&N said. "The new NookColor Reader's Tablet, introduced just eight weeks before Christmas, is the company's number one selling gift of the holiday season."
In addition, B&N said that even as its physical book business continues to grow, it now sells more digital copies than it does of the dead tree versions. On Christmas day alone, B&N logged more than 1 million eBook sales.
