Speaking at Apple’s annual shareholders meeting today, Apple CEO Tim Cook said Apple TV made more than $1 billion of revenue in 2013. Cook has often referred to the set-top box as a “hobby,” but said today, “It’s a little more difficult to call it a hobby these days.” The news comes amid a recently announced deal on current Apple TV models that has fueled speculation regarding an upcoming Apple TV hardware update. Cook also said during the meeting that 40 billion iMessages are sent daily, along with 15 to 20 million FaceTime calls. [via Reuters]
