Acorn TV
For a reasonable monthly fee, you can watch British programming on your laptop, iPad, phone, your Smart TV, your Apple … you get it. Acorn fortunately offers their content on every platform one can think of, providing a good amount of British television content. And since they have a Foreign Language section, you can also find a few Italian, Dutch, or Scandinavian productions.
Some of their content is of course also available on Netflix or Hulu, but Acorn has it in one place, and includes a few shows that aren’t available on U.S. streaming services. And of course – lots of Agatha Christie.
