New York - I'm in Manhattan, at a hotel in Times Square. It's been more than a year since I was here. And I'm struck by the increase in active signage, even here, the heart of inventive building-side ads. Just about every building here in Times Square is coated with multicolored, programmable screens. Some of them just do text; others are nearly as good as a television.
So just an observation, but as flat-screen technology gets better, as LEDs get brighter, we're going to see a lot more TV-like screens replacing static billboards. Here in NYC they've got 'em outside subway stations and on taxi cabs. Cities are going to look ever more like Blade Runner.
