Ask most people why they still buy a movie or a show outright in the age of the all-you-can-eat subscription, and you’ll get a shrug and a tossed-off comment about wanting an old favorite on hand without having to hunt down which service currently carries it. That argument got even stronger this month, when Apple began upgrading purchased TV shows to 4K for free. That’s roughly 50 titles so far, including all seven seasons of Mad Men and the first season of Star Trek: Strange New Worlds, bumped up at no extra cost for anyone who already owned them in HD.
