I visit home every 3-6 months and end up watching a lot of TV. It’s something I did a lot as a kid but scarcely do now, mainly because 1. I don’t own a TV 2. The Internet is a good substitute. 
Still whenever I think about TV, I miss how de-stressing and cognitively easy it was. Even though the you can find the whole gamut of content on the internet, I hardly associate my laptop with relaxation or comfort. 
TV vs Internet Amount of Content - Limited by provider vs Effectively infinite
Interaction style  - Focused vs Distracting. Your TV usually occupies a prominent place in your living room/house and is positioned so you can sit back and just watch, interacting minimally with the remote. Laptops need a mouse/keyboard/trackpad to be worked with
Multi-tasking - Hard vs Easy
Keeping tabs on two things is painful on a TV vs simple on a computer. 
Screen size - TV screens are significantly larger than laptop screens
Application distraction - You don’t get emails and notifications on TV. Interruptions from the TV itself are minimal.
Content Quality (Physical) - TV content is consistently of higher quality, though this gap is narrowing. 
Production Quality - Content for the TV is usually of higher quality, though this distinction is near meaningless now. 
Reliability - The TV rarely fails to load and doesn’t buffer. 
Content manageability - Not in your hands or difficult on the TV, multiple solutions available to manage content on the Internet.
Exploration - Poor on the TV (flicking through various channels) vs great on the internet.
TVs are more reliable and with less content with more production value but you’re less in control of the experience. Also, because of the way we use them, TV consumption is a more enjoyable . TVs  feel grandma-ready, there’s less to learn to get what you want done on a TV, not so on a laptop.
