Yep, it's hard to believe it exists for free and with not a lot of ads when you have a good ad blocker... though the content creator's ads are inescapable, which I think is ok since they're making a little money in exchange for what, your little inconvenience for 1 minute or so - if you're not skipping the ad, which you aren't, right??) - after which you can watch some really good content. The history channels on YT are amazing, maybe world changing - they get people to learn history and actually enjoy it. Same with some match channels like 3brown1blue which are just outstanding, and many more.
