The expansion fits Amazon’s strategy of providing more than just an e-reader and digital bookstore. The retailer is deeply concerned with building an entire ecosystem encompassing not just book lovers, but authors and publishers too.

Amazon’s Kindle is the leading e-book reader with Sony’s reader coming a distant second.

Amazon designed Kindle to give an exceptional reading experience. Kindle’s screen is as sharp and natural as reading ink on paper. It is also easy on the fingertips and has been made for ambidextrous use.

Analysts believe that the e-reader manufacturer could eventually find a lucrative market in educational institutions, where students would need only to carry a lightweight device. Though such an offering would depend on having textbook publishers onboard, something they are diffident and reserved to do until they can establish a profitable business model.

Amazon, however, suffered a hinder when four US Universities, under pressure from the US Justice Department, agreed not to promote the use of Amazon’s Kindle DX electronic reader in the classroom except for students who are blind or have poor vision. The Department had sought the agreement under the Federal Americans with Disabilities Act, which proscribes discrimination on the basis of a disability.

Amazon has announced its Kindle Development Kit, which enables software developers to construct and upload “active content” for the Kindle wireless- reader device. Wherein the content possibilities could include travel books that recommends activities based on real time weather and current events, cookbooks that suggests menus based on the size of the party, word games and puzzles.

Till now only available for US based authors, the Kindle Digital Text based platform allows those writing in English, German or French to upload and sell their books to Kindle owners across the world. Even the authors or copyright holders can set their own prices. Amazon would take a cut of 65 percent in the sales leaving the remaining 35 percent for the author. Although the service isn’t hugely popular as of now, increased activity on this channel could disrupt the traditional publishing industry to a greater magnitude.

The kit proposes access to programming interfaces, tools and documentation to build content for Kindle. Developers can build content leveraging the Kindle 3G wireless delivery system over Amazon whispernet networking and the high resolution electronic paper display that looks and reads like real paper. Kindle attributes a battery life of seven days with wireless activated on the device.

Kindle delivers the spontaneous choices for reading on demand. All newspaper subscription starts with a risk-free two week trial. A revolutionary latest display technology will be an advantage for e-reading, in addition to upload the new versions of books and their sequels which can be read comfortably at any angle for lefties as well as righties.

The reader is already challenging traditional way of reading books and newspaper. Higher popularity of the device could mark a permanent shift for some associated industries in the same way that Internet has affected newspapers.
