Do I need a TV license if I want an Apple TV?

that depend on the laws of your country, where I live you pretty much need to pay media license if you have broadband in any form or another

apart from the government-enforced laws of your country, the appletv is not viewed as a different product than an ipad, and you will not need to pay anything to apple apart from the purchase price.

What do you mean a TV license? You just need a good Internet connection where the Apple TV will be placed and a TV with an HDMI connection and finally a good quality HDMI cable.
