The technology was developed and improved, and by the late 60's, it had become advanced enough to allow the scientists to construct geometric shapes. Today the progression in high-speed digital processing, materials, and advanced manufacturing technology has made full color, bright plasma displays possible. Digital television is now a reality -- but you're not going to see it the way it was meant to be seen using yesterday's TV sets.
