Amazon.com Inc is considering a new e-book subscription service called Kindle Unlimited, that aims to replicate popular video-streaming models for the digital books market, according to several online reports and a test page that briefly appeared on the Internet retailers website. The page, spotted by tech blog Gigaom but since taken down, touted a service that for $9.99 a month, would grant unlimited access to more than 600,000 titles including popular books Life of Pi, and Water for Elephants, as well as blockbuster franchises like the Hunger Games, and Lord of the Rings. A brief promotional message described the service as available on any device. Other details remained unclear, however, and Amazon did not immediately respond to requests for comment. Unlike video streaming, which is dominated by services such as Netflix Inc and Amazons own Instant Video, few on-demand, buffet-type options exist for digital readers beyond smaller players such as Sribd.
