In 1996, Stan Honey developed a way to track hockey pucks with a blue halo as seen by television viewers. It was assumed at that time that viewers had a hard time keeping track of the puck. Released as the FoxTrax puck, it was not a success but led to the 1998 formation of the Sportvision company and later that year the development of the 1st & Ten computer system, which generates and displays the yellow first down line that a TV viewer sees during a live football broadcast. The system became a major hit with television viewers when used during a broadcast of the Super Bowl. It has since become part of all standard American professional and college football and Canadian pro football broadcasts.
Another popular Sportvision product is seen in broadcasts of NASCAR races. It is called RACEf/x, and creates virtual flags above the cars to make them easier to follow by the viewers.
