Today something rare is happening: an Apple keynote with possibly zero hardware news. The company recently sent out invitations for a March 25th press event with the words "It's show time" and an animated countdown clock -- the sort of old-timey touch you simply don't see in theaters anymore. That's as clear as a confirmation as any that Apple is about to unveil is long-awaited video streaming service. Other than the company's various original content deals, ranging from movies to TV shows, we've heard surprisingly few details about how the service will work, what it will cost or what it will include.\n\nGiven that Apple already announced some minor iPad and iMac updates last week, we expect the company will use most of its allotted time to do a deep dive on the service itself, with very few, if any, asides related to hardware. In any case, all will be revealed soon. Join us today at 10am PT\/1pm ET and follow along with our liveblog straight from the Steve Jobs Theater in Cupertino.
