Why does Apple not advertise a lot for Apple TV?

Well, I do not know why Apple has not advertised Apple TV, like it does for i pod or i phone or Mac line of products. On the other hand, there are not many ads on the podcast which you would view on your TV using Apple TV.

I am currently pursuing MBA program at Ivey School of Business in London, Ontario, Canada. We had a talk from an executive from Dentsu (an international ad agency with a huge base in Toronto). He showed us a video from 1984 launch of Mac (Steve Jobs' famous and open war against IBM was launched following with with the Superbowl ad. Well, back to the point, I asked the executive what he thought about future of advertisement on devices like Apple TV. He said that I was among early adopters and in five years from now, Apple TV could become a dominant player in its segment and advertisements will start flowing as people will find a way to leverage. So, my question is whether I am really an early adopter of this fabulous product. I will be glad to hear if there any other people who find themselves talking about Apple TV but noone in the audience has even heard about it.

May be, Apple has a strategy behind not promoting its product aggressively at this stage. Or, they are developing the product further, in the back office! Watch this one of the only few ads on Apple TV and let me know what is the message.
