For the 2015 season, ESPN introduced a new on-air appearance for baseball. Among its changes were a new, persistent K-Zone Live graphic, consisting of a faded white rectangle that is overlaid live atop the strike zone on the home plate camera angle at all times. A new K-Zone 3D graphic, with ball trails and a three-dimensional box representing the strike zone, can also be used during replays. The new live K-Zone graphic was criticized by viewers and the media for being potentially distracting, drawing comparisons to baseball video games and Foxs "glowing puck" from its NHL coverage.
