A:Answer On most smart TV's like Vizio, you will have to hook it up to your WiFi in order to use their TV apps but I would caution you on doing that as Vizio (and other Smart TV brands) is known to harvest your viewing data among other information you may not wish to let them have. You can, however, hook your Roku or Apple TV to your WiFi and then access Netflix that way. Netflix and others like HuLu require a paid monthly subscription to view their content. If you have an Amazon FireStick and have Amazon Prime, you have a lot of viewing content included with the Prime subscription. Hope that helps!
