September 1998 was when ESPN first introduced it in a pro football broadcast.
A Natzo is a name written down on paper, then outlined with a color marker, then outlined with another color marker until it reaches the end of the page.
The 1st down marker indicator was started by John Madden in the Madden football game series, long ago. He did this to tell people where they had to get to in the game, and the NFL used this idea to have what we use now.
Legal for what? It has to be moved ten yards to establish a "first down" or a new set of downs. This occurs after a kick off return, a punt return, an interception, a fumble recovery, or when the ball has been moved past the first down marker.
A fumble is down when the recovering player is down or when the ball goes out of bounds...so yes, if the ball is fumbled forward and recovered by the offense, or goes out of bounds, past the first down marker, it is a first down. The exception is on fourth down. In the NFL, only the player who fumbled the ball can advance it on fourth down.
2nd down =]
You have to get a first down. When you get a first down, it moves the chains and it is first down. When you have a first down and the are no penalties, it is a first and ten.
In the Canadian Football League, a team has three plays to make a first down. In the National Football League, a team has four plays to make a first down.
The specification of the first football were laid down in 1872. The first footballs were used by Football association who played at that time.
if any part of the football is over the chains then the answer is first down
It goes to the second down
