Hi,
At Amazon, we've always been obsessed with having every book ever printed, and
we know that even the best reading device would be useless without a massive selection of books. Today, the Kindle Store has more than 260,000 books available, plus top newspapers, magazines, and blogs. This is just the beginning. Our vision is to have every book ever printed, in any language, all available in under 60 seconds on Kindle. We won't stop until we get there.
This is an amazing technology.
Also, I believe its popularity is going to increase significantly in the future.
Hope it helps.
Cheers,
