There are so many different streaming services you can subscribe to these days, all with different purposes. From sports games to movies to books, there's a streaming service for everything. One thing they all have in common is the annoying monthly fees. If you're looking for a streaming service for documentaries, Curiosity Stream is perfect for you. It's from the same creators as Discovery, so if you're a fan of that style of content, you'll want to check out Curiosity Stream.

And for a limited time, you can avoid those monthly fees. There's a big discount at StackSocial right now that'll get you a lifetime subscription for just $180. It normally retails for $400, giving you a savings of 55% on this subscription. If you're interested, act fast. Just remember that this offer is available to new users only. 

From history to deep space to the wilds of nature, this streaming service gives you instant access to award-winning, educational digital content. Launched by Discovery Communications founder John Hendricks, Curiosity Stream delivers documentaries that cover a wide range of topics. Learn about deep space from Stephen Hawking, experience an excavation at Pompeii and travel the world experiencing new places -- from remote jungles to European cities -- all without leaving home. 

The Curiosity Stream standard plan includes streaming and downloadable content so you can watch offline. It's easy to search, bookmark or resume viewing, and it's compatible with both mobile and desktop devices as well as smart TVs, though if you plan to use an older device, you'll want to double-check the system requirements before your purchase. For example, requirements include Android and Android TV 5.0 and up, iOS 11 and up, Apple TV 3rd gen and earlier via AirPlay, and Xbox One, among others. There are regular content updates, too, so we're betting it would take you more than a lifetime to watch it all. Just be sure to redeem the offer code within 30 days of purchase.
