Smithsonian Networks will offer an over-the-top subscription service that will feature original nature and wildlife content, the network said Tuesday.

The new service, dubbed Smithsonian Earth, will be offered on Roku players and Apple TV players for $3.99 per month, with one percent of subscriptions sales donated to the Smithsonian Institution research and conservation initiatives, according to network officials.

Smithsonian Networks will offer new subscribers a seven-day free trial of the service, which will offer 4K content through the Roku 4 streaming player.

Smithsonian Earth will feature original nature/wildlife documentaries and short series refreshed on a weekly basis, according to network officials.

“With Smithsonian Earth we are looking to satisfy the strong consumer demand for visually stunning unique nature and wildlife programming,” said Tom Hayden, president of Smithsonian Networks in a statement. “Subscribers to this service can view the beauty and diversity of the natural world across multiple platforms and in spectacular 4K.”
