The shape is right there in the middle of the invitation to this year’s much-sought-after* World Wide Developer’s Conference: A black square with rounded corners.
See it? That’s Apple TV, which took the form of a black cube five years ago and hasn’t changed since.
Apple TV’s function hasn’t changed either: It’s a set-top box that plugs into an HDTV and connects to the Internet.
Steve Jobs called it a hobby, and although it’s been generating more than $1 billion a year for at least three years it’s still one of the lesser stars in Apple’s product line up. It never did for television what the iPod did to music or the iPhone to telephony.
Yet now, according to the invitation, it’s about to become “The epicenter of change.”
How it gets from here to there is still not clear, but there are plenty of hints in the leaks, rumors and prognostications that cross my screen several times a day.
According to the Apple rumor mill, here’s what we can expect at WWDC15:
- A new Apple TV: Same shape, more power, more memory, improved OS, with support for Siri and other services. (BuzzFeed)
- A new Apple TV remote: With touchscreen and Force Touch haptic feedback to streamline navigation. (NYTimes)
- An Apple TV SDK: A software developers kit to open the platform to an army of programmers ready to write games, educational software, home-control apps, iPhone extensions, etc. (9to5Mac)
- A new App Store: This is where the new Apple TV apps will be bought and sold. (BuzzFeed)
- A new Apple Music service: The marriage of iTunes and Beats with which Apple hopes to break into the market pioneered by Pandora and Spotify. (9to5Mac, Billboard)
- A new, bundled live TV service: If the price is right and the content includes ESPN, this could be the “change” TV has been waiting for. (WSJ)
p.s. It doesn’t fit the Apple-TV-as-epicenter-of-change theme, but according to several sources, including Global Equities Trip Chowdhry, Apple Watch programmers will also be getting a full-fledged SDK at WWDC15.
The show starts with a Moscone Center keynote the morning June 8. I’ll be there.
