I’m a little behind on the technology. Would you mind please explaining what do these devices do? Like the Amazon TV stick? I’ve seen it on Amazon available for pre-ordering.
these devices provide an interface for all of these different streaming companies. you buy the “stick,” plug it into your tv, and access these streaming services. You will have an account with Netflix/Amazon, for instance, and sign into that account and access the content they provide to you for your account.
There are many free programs also - news and such. Kind of like a “store” for all of the apps smart phones use.
