What are your favourite TV channels ?

There are hundreds of channels on my TV and I enjoy watching a lot of them. However, my favorite channels are National Geographic and Discovery. I like them because it is always interesting for me to learn something new. I can just sit down on a sofa, push a button on the remote controller and enjoy learning about space, animals or climate changes. I believe National Geographic and Discovery are excellent examples of channels that can not only help you to rest mentally, but also can teach you a lot about our world!
