Retractable TV chords

  I used to work in the VCR/TV repair business, I can't tell you how often people would trip over the VCR or TV electrical chords. Most cords are very long. Wouldn't it be great if TV cords where retractable? It would be so nice not tripping over a 36 inch TV chord while you're holding it, most people don't know how to wrap it up nice. I thought of this idea about 5 or 6 years ago.
