Most of their programs can be seen on their own website.
I am puzzled with one thing: Why it is for US citizens only?
I wanted to be an US citizen ages ago and was deported.
Therefore, I have no choice but to use an VPN and see America on the Internet only.
I can highly recommend Proton VPN.
They have free and paid option.
Free option is working well. It is unlimited, fast, and it is for 3 countries - US, Japan, and The Netherlands.
If it wasn't for Smithsonian Channel, I wouldn't had tried an VPN ever.
