Once upon a time, football was the cutting-edge sport in America. Since it was played in a confined space of a larger playing surface, the sport was perfect for television. In fact, the popularity of football is linked to the 1958 NFL Championship game between the Baltimore Colts and New York Giants.
Ironically, as technology has evolved, football has mostly stayed the same. HD television has opened up new horizons on ice and the baseball diamond for sure.
In football, the networks now employ former officials to discuss replay calls that elongate the game further each season.
