Many of the movies and TV shows that you have downloaded from Apple's iTunes Store will soon be available for downloading onto other devices or via streaming to your iPhone, iPad, Apple TV and other devices, the website reported today (Thursday). The system, named iTunes Replay, is currently being tested internally, but is on The Edge of a final launch, the website said. Movies on sale in the iTunes store that are eligible for streaming after purchased will be designated by an arrow. Some titles will only be available for downloading five times. "We don't know how streaming will count towards that limit," the website said.
