Kindle Outpaces Paperback Sales

Amazon has revealed that it has sold more Kindle ebooks than paperbacks in the U.S. during the final three months of 2010. The milestone has come sooner than expected.

Amazon has revealed that it has sold more Kindle ebooks than paperbacks in the U.S. during the final three months of 2010. A similar pattern has continued during January 2011 with 115 ebooks being sold for every 100 paperbacks. The figure only relates to the U.S. market and the number of ebooks sold on Amazon’s own e-reader device, the Kindle, which now accounts for 41.5 per cent of the e-reader market. Amazon is expected to sell more than eight million Kindles this year, up from 2.4 million last year, according to Bloomberg. The figures exclude any free ebook download offers but include those made via the free Kindle iPhone app and tablet and desktop apps.

Why are so many objects in space shaped like discs?

It's one of the most consistent patterns in the unviverse. What causes it?

Videos
  • Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
  • Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
  • Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
