High definition television (HDTV) is the highest form of digital television. It has a 16:9 aspect ratio, which is similar in appearance to a movie theater screen. HDTV has a couple of advantages over the old analog TV format -- the wide screen and the resolution.

The wide screen is good on our eyes, we see the rectangular wide screen images better than the old square format. Basically, our eyes see better from left/right compared to up/down. The wide screen will also let us see more of the on-screen scene, which is great for sports and movies.
