40-episode box set is $30 ($16 today) on Apple TV.
When you purchase access to this item, you can permanently download it to your iPhone, iPad, Mac, or PC. Once downloaded, you can access this without an internet connection, and Apple can't remove it from your device.The term "album" by itself did originally refer to something physical -- a collection of photos bound into a book by a glue made from egg whites ("albumen") -- but the semantic shift to "album" meaning any kind of collection offered as a single unit happened well before "record albums" were a thing.
But the term "box set" has not experienced a comparable semantic shift, and still implies the presence of an actual box.
