This holiday season, it’s been impossible to buy an Amazon Kindle.. The popular ebook reader. Many say due to the product’s endorsement by Oprah.

We’ve been making all of our books available for Kindle readers, and seen substantial sales.. especially for our popular book on Twitter (“Twitter Revolution: How Social Media and Mobile Marketing is Changing the Way We Do Business & Market Online“).

According to the New York Times. Kindle sales have helped increase sales of electronic books:

So far, publishers like HarperCollins, Random House
and Simon & Schuster say that sales of e-books for any device —
including simple laptop downloads — constitute less than 1 percent of
total book sales. But there are signs of momentum. The publishers say
sales of e-books have tripled or quadrupled in the last year.

Kindle version of “The Story of Edgar Sawtelle” by David Wroblewski, a
best seller recommended by Ms. Winfrey’s book club, now represents 20
percent of total Amazon sales of the book, according to Brian Murray,
chief executive of HarperCollins Publishers Worldwide.
