Well, so how is Apple going to advertise Tiger to people? A new commercial or none at all. I would find their opening movie a great commercial for TV, without the dark ending but with all the things that are in Tiger. Flash of the program's or feature's name with a quick video of it in work. It would be Spotlight, Expose, iChat, Automater, Dashboard, Safari and few more. Maybe some games being played on it like the Sims, WoWIII, and the Incredibles. Then end with the Apple logo, with http://www.apple.com. I would find it would perk everyones attention when watching TV. Especially the music.
