720P format is one of HD protocol when it was established. But with 720p TV on market disappearing and only available on elcheapos and smaller TVs, one wonder if 720P is a dying dinosaur.

The argument was that 720p is progressive and better for sport and high action programs, but with 1080P capable TVs, that argument is not true anymore. 720p was the preferred format for ABC and Fox network, but I am not sure if they have moved on to 1080 format or not.
