Not sure iTunes "cracks" tv. !! Search would be good though.
Apple has insisted on calling its Apple TV set-top box a "hobby," even though the most recent version appears to be selling well. But Steve Jobs said shortly before his death that he had "finally cracked" a way to make TVs as simple and elegant as the iPhone or iPad. And the talent he trusted to see that task through is reportedly none other than Jeff Robbin, the same software engineer Apple brought on in 2000 to build iTunes.
Jobs told author Walter Issacson during an interview for his recently released biography that he wanted to make using a TV as simple as he had made using a smartphone or music player. “I’d like to create an integrated television set that is completely easy to use,” he told Issacson. “It would be seamlessly synced with all of your devices and with iCloud. It will have the simplest user interface you could imagine.”
“I finally cracked it,” Jobs said.
