But Youtube serves a vastly under-discussed purpose: to educate. Here are 7 of the very best educational Youtube channels.
This channel is best watched when you've exhausted the rest of the internet.
Home to refreshing ideas and eye opening stories, TED is a channel of publicly delivered speeches by kick ass academics and other people of note. Always captivating, often addictive. TED is less about teaching you facts and more about opening your mind the possibility things don't work the way you thought they did.
Where to start: Do Schools Kill Creativity?
If you're not a numerical nerd yet, you're about to be.
Run by Brady Haran (hard as nails, posh as cushions), watch him meet and interview great academics who have all kinds of explanations up their sleeve. Trademarked by their classy brown paper, I personally love any videos with the ever awesome Hannah Fry.
Where to start: The Scientific Way to Cut a Cake
CGP Grey is like a brilliant encyclopaedia you've wired to a (slightly overcharged) power source.
Fast paced and consistent in tone, this channel covers topical knowledge and insights into how things work. If you haven't see his 'UK Explained' video then you're one of the 5 people on Earth who missed it. His content is somewhat infrequent but never disappointing.
Where to start: Humans Need Not Apply
Khan believe anyone can learn anything.
Less for entertainment value and more for an afternoon with a pen and notepad, this channel will teach you Chemistry, Algebra, Finance, Biology, Physics and whatever else you missed out on at university. Not quite lunch watching material, Khan is more for the serious-about-learning learner.
Where to start: Introduction to the atom
Is everything the Green brothers produce brilliant?
Crash Course is expertly animated and well explained. More of an entry level channel than Khan, learn psychology, astronomy, literature and most branches of science. Best watched on a Sunday when you can dedicate three hours to watching one of their playlists back to back.
Where to start: Intro to Psychology
