Marketing Land has assembled this comparison chart showing what subscription and rental services can be used with the new Google Chromecast, the Apple TV, and the Roku streaming boxes. The new Chromecast, which costs just $35, plugs into an HDMI port on a television, and needs to be charged via a USB connection. The Roku box is perhaps the most direct competitor for the Apple TV, with the Apple TV supporting AirPlay mirroring and streaming from iOS devices while the Roku delivers a number of additional content sources.
