It's from Amazon and while its Freevee service already exists, it's about to add a lot more content. All of it without charge - although you may need to sign up for a free Amazon account to access it. You do not need to have an Amazon Prime membership. 

"Over the next few months, Freevee will launch 12 MGM channels, including single-title channels The Pink Panther, Stargate, Green Acres and The Outer Limits, alongside branded channels such as MGM Presents, MGM Presents: Action and MGM Presents: Sci-Fi, which will be programmed with premium movies and series including Capote and Red Dawn. They will join Paternity Court, In the Heat of the Night, The Addams Family and Teen Wolf, all of which are currently available on Freevee."

You will probably need a VPN set to the U.S. to get the maximum out of the service.
