What all needs to be bought with an apple tv?

I know apple likes to be cheap and stuff… But i want apple tv… What can it do? And do i need an iPod or iPhone to have one? And also what do i need to buy separate if i need to?

The apple TV can stream Netflix and Hulu and many other apps like NHL, NBA, MLB, but those only work if you have a paying subscriptions to each of the services. But you can go on the internet and watch YouTube on the TV.
You don't have to have an iPod or iPhone to use it.
All you need is a hdmi cable and a tv with hdmi input.

I have recently bought one i was disappointed
basically if you don't have netflix don't buy it
it has netflix, news, youtube, sports, koren tv aha
and a movie renting area
everything costs money except youtube and news
NO internet surfing

one cool thing you can mirror your iphone 4s or 5 /s/c on your tv thats it

You need an HDMI cable and a home wireless system.

It will give you access to your iTunes video. It is good if you have purchased a lot of Apple media.

The Google ChromeCast ($35) is not tied to the iTunes vending machine and tends to give you nearly as much as the apple TV.

You just aren't very bright, are you?
