Fire TV also offers music channels like Pandora and "Free Time", a customizable interface for children.

Amazon's announcement comes as the online retailer faces increasing pressure to boost its bottom line after years of furious growth. As more Americans shop online, Amazon has spent heavily to expand its business into new areas from movie streaming to e-readers and groceries often at the expense of its profit.
Meanwhile, Amazon.com Inc. has invested heavily on making TV shows and movies available to customers who pay $99 a year for Amazon Prime. Amazon recently boosted the annual fee to $99 from $79 annually. Members benefit from two-day shipping of certain items and access to videos including original series like "Betas" and "Alpha House."
Currently, the service relies on third-party devices like the Roku box to stream its programs to TVs.
