10 Ways Technology Is Changing Football

摘要

When you sit down to watch football on Thanksgiving, remember this: Even amidst the bone-crunching blocks and tackles, there's technology. Over the course of a century, the game's helmets, jerseys, gloves, and even undershirts have evolved to keep players safer and warmer.But those advances were just a warm-up for more recent innovations. Today, mammoth scoreboards use millions of light-emitting diodes, enabling fans to watch high-definition replays while they sit in the stands. And television broadcasts now employ superimposed lines on the screen, allowing viewers to more easily identify first-down territories. Technology has even put the venerable tackling dummy on the sidelines, as pro and college programs have begun turning to robots to take more hits in practice.
