Fortunately, Steve Jobs had the idea for Apple TV (a real TV not the little box) that could give Apple another runaway success. With their designer Ive's and the UI designers still around, I see no reason why Apple TV won't propel Apple for many years to come.
I do not think AppleTV is the same as that TV you are talking about. AppleTV turns that large screen in your living room that used to only get data from a cable into a large Internet-connected display that shows on-demand photos and video (soemtimes from those phones and tablets). In a sense, the TV just is the largest display in the house, in a place where it is convenient for multiple people to look at it from comfortable chairs.
Can you source that last claim? It's a rather large claim, and one I'm not willing to take on face value. I can believe that TV is fading, but that the under 30 crowd "mostly" watch video on those mediums is a bit of a stretch to me.
"Apple TV" is a 5.5 year old product, currently in its third generation. If this was something that could be won by an "idea" then it would have succeeded by now. The current product looks good, basically "almost as nice as cable for less money" for most users. But I wouldn't pin any long term hopes on a set top box.
