PBS and PBS Kids apps have just been released for the Fire TV. These apps have been featured on the Fire TV’s “coming soon” list for quite a while. Both apps feature a slew of great video content completely for free. Once installed, both apps need to be activated, but unlike other apps which need activation, a cable subscription is not required to activate these apps. All you need is a free PBS.org account. The PBS Video app features full length episodes of Sherlock, Downton Abbey, Endeavour, Breathless, and many more popular TV shows.
