Effective 6/26/2016, Sony's PlayStation Vue service has added Roku and Amazon Fire apps to their offering which brings AFL to those platforms along with it. Since you can subscribe to the service via Roku or Fire boxes without the need to own a Playstation, it adds another way to get footy onto your TV and avoid subscribing to a full cable TV subscription. High speed internet will still be required, of course.
Pricing probably means it exists as an alternative for the "cord cutters" and no so much for other internet based viewers. The service carries Fox Sports 1 (FS1) and Fox Sports 2 (FS2) in it's base offering ("Access" package) for $29.99 per month along with many other channels.
