Moreover, DRM enables content industry to control where content can be played, known as geoblocking. For example, I live in North Europe, and the titles that are available in 'official', DRM-controlled sources, such as Netflix, are noticeably different than in North America. Maybe Netflix only has distribution rights for some title in the US market, so when I try to look it up the search comes back empty. What DRM allows Netflix is to still sell one and the same subscription globally. The content you can view is not tied to your account's registered post address or such, but which physical region of the Internet you are actually accessing the service from currently. When we were visiting the US, my spouse was able to play titles with her Netflix subscription that are not available at home, because she was connecting to the US DRM servers from the WiFi of our Airbnb in California. For our flight home, she put her phone in flight mode and was able to watch cached titles during the flight. But as soon as she turned on her data in Europe, the titles magically disappeared in thin air, as the EU DRM server realized the geoblocking violation and revoked her license to those titles.
