The clever engineering behind the virtual yellow first-down line you seen on TV for NFL games. Subscribe to our channel! http://goo.gl/0bsAjO Since the late 1990s, the virtual yellow line has been quietly enhancing football broadcasts by giving viewers a live, intuitive guide to the state of play. The graphic is engineered to appear painted on the field, rather than simply plopped on top of the players, so it doesn't distract from the game at all. The line debuted during a September 27, 1998, game between the Baltimore Ravens and the Cincinnati Bengals. It was developed by a company called Sportvision Inc. and operated by six people in a 48-foot semi-truck parked outside the stadium. ESPN was the only network that immediately agreed to pay the steep price of $25,000 per game. Before long, other companies began offering the yellow line to the other networks, and now you won't see a football game without it. Vox.com is a news website that helps you cut through the noise and understand what's really driving the events in the headlines.
