The Denver Nuggets have built a new scoreboard for the Pepsi Center and claim that it is the largest in the league. Check out the time lapse video showing the construction. Judging by the video it certainly looks massive.
The scoreboard will broadcast in a true 16:9 aspect ratio at 1080p HD and boasts a surface area of more than 4,400 square feet, making it the largest in the NBA or NHL. The length spans 3-point line to 3-point line for basketball and blue line to blue line for hockey.
