Amazon has launched the Amazon Fire TV, a tiny set-top box that combines video with music streaming and gaming and is designed specifically to challenge the Roku and Apple TV. Amazon claims that the devices design is influenced by the shortcomings of other set-top boxes on sale and by the growing demand from its customers for multimedia content without being stuck in a closed ecosystem. The result, the Amazon Fire TV, is a tiny black box packed with a serious smartphone-level processor, 2GB of RAM and will ship with a remote control with an integrated microphone, meaning that it will respond to voice commands too. But perhaps most intriguing is that Amazon claims the box is a gateway to an open, rather than closed, ecosystem and that as well as hosting Amazons own content, the device is about to receive content from a host of partners including Netflix, Hulu, ESPN and Disney with many more to follow.
