Apple has increased the time a user has to finish or rewatch a movie rented from iTunes from 24 hours to 48 hours for U.S. users, according to the company’s updated support document. Users in the U.S. users have 30 days from the time they rent a movie to begin watching it, and now they’ll have twice as much time to finish it. The 48 hour window to watch an iTunes rental has been available since the beginning of iTunes movie rentals in Canada and the U.K. — among other countries — and it’s not entirely clear why the U.S. had a shorter time limit. The company also recently made 4K movies available for rent at the same price as HD movies (but they can’t be downloaded for offline viewing).
