Yes, some of it looks a little dusty these days, but it's still possible to trace many of this year's cutting-edge winners back to their ancestors from the past two decades; as they say, innovation begets innovation. Dig the Jawbone Bluetooth headset, a winner this year in the gadgets category? Check out the monstrosity that started it all. Excited that consumer-level holographic storage is just around the corner? Might want to scope our 1992 prediction. From the 3-D camcorder bound to revolutionize home movies to the V-22 Osprey (finally flying 19 years after we first covered it), join us in looking back at 20 years of innovation. As for the next 20, this year's picks are only the beginning.
