Amazon calls on software developers to build and upload active content that will be available in the Kindle Store later this year.
The new Kindle Development Kit gives developers access to programming interfaces, tools and documentation to build active content for Kindle.
"The kit opens many possibilities (and) we look forward to being surprised by what developers invent," said Ian Freed, VP of Amazon Kindle.
Starting February, participants in the limited beta will be able to download the kit, access developer support, test content on Kindle, and submit finished content.
