Releasing movies and TV shows simultaneously around the world would cut piracy a lot. That's one pretty clear criteria: the content is sold in a digital format somewhere but not in your home country.

Take the Sherlock TV series for example: who wants to wait for two years for a new season, and then an additional two months for it to arrive in your particular country? In Finland the series is shown on a state-funded channel who don't even get any money from you watching the show on their channel.
