The downside to this is eventually it will probably become cheap as hell - or at least one side of it. Anyone remember in MINORITY REPORT when he was pouring a bowl of cereal and it activated the advertising on the box that "came alive" and wouldn't shut up? Newspapers were animated, had 'breaking news' which is was kinda cool tho.
That was another thing they were working on was advertising ... product boxes and entire sides of buildings.
