Last night, while preparing a class, I was looking for cases of brands that were innovative at their time but were no longer around. I went online to confirm my assumptions. To my surprise, Polaroid, which was on my original list, is actually going through an interesting revival. I was positively surprised to learn about a product called PoGo™, which they are calling an instant mobile printer for mobile phones. It's an innovative way to share digital photos directly from a camera cell phone or digital camera, instantly. With the proliferation of mobile phones, it makes a lot of sense.
