Save 25% on this streaming service that hosts over 2,000 documentaries

Hey, we love Netflix and Hulu, but let's face it: The whole setup doesn't exactly encourage active viewing. For all the binge-watching we've done, it's tough to expand our horizons or learn anything new - except for how many episodes of "The Office" it takes to make us fall asleep.

It was only a matter of time before a streaming service would come along that actually welcomes and challenges curious minds. With a library of over 2,000 documentaries, CuriousityStream lets you binge to your heart's content - and it's more than just empty calories.

The service includes a ton of established, award-winning films, plus a mix of originals that boast some high-profile talent. You'll find documentaries on nearly every subject imaginable, from the possibilities of space travel to the secrets of lost civilizations, narrated and presented by names like David Attenborough, Stephen Hawking, and Mike Rowe. The more you watch, the more you learn with algorithms that tailor that next documentary to your personal taste.

Sign up, and you can access any of the films from a range of devices. A 3-year subscription to CuriosityStream is now 25% of the list price.
