The Yellow First Down Line First Aired In 1998. It Came From A Hockey Puck Fans Disliked

ESPN aired the first computer-drawn first down line on September 27, 1998. The idea grew out of a glowing hockey puck.

The yellow first down line first aired on September 27, 1998, during ESPN's Sunday night telecast of the Baltimore Ravens and Cincinnati Bengals. According to ESPN, the company Sportvision developed it with the network, and ESPN executive Jed Drake suggested the yellow.

The hockey puck

The system grew out of FoxTrax, which put a blue glow around the puck on Fox hockey broadcasts starting in 1996. Mental Floss reports that hockey fans disliked it, but the idea of drawing on a live picture carried over to football.

Why players seem to run over it

The line sits on top of the picture, not on the field. Before each game, technicians build two color palettes. Turf colors, mostly greens and browns, turn yellow when the line is drawn. Colors on the other palette, such as uniforms, shoes, balls and flags, stay as they are. So a cleat on the line keeps its own color.

What it cost

Mental Floss reports that the early setup took a truck, a four-man crew and five racks of equipment, and that it cost broadcasters about $25,000 to $30,000 a game. CBS aired a rival system from Princeton Video Image a couple of months after ESPN's debut.
