meets though for the majority of its existence there were only two meets per year. The spring meet starts one week before the Derby and continues until early July. The Kentucky Derby is held the first Saturday in May and the Kentucky Oaks is run on the Friday before the Derby. A fall meet picks up in late October and closes Thanksgiving weekend in late November. A third meet in September was added in 2013. In addition to the track, clubhouse and stables, Churchill Downs also contains the Kentucky Derby Museum which focuses on the history of the Kentucky Derby and Churchill Downs. The museum also contains a number of exhibits exploring the training and racing of thoroughbred horses. It includes a 360-degree cinema that shows the short film "The Greatest Race", a documentary about the Kentucky Derby. The museum is normally open year-round. In October 2013, Churchill Downs began installing a new, ultra high-definition video board built by Panasonic, which became operational in time for the 2014 Kentucky Derby. Called "The Big Board", it measures wide and high, with the bottom edge off the ground, and weighs . It was constructed along the outside of the backstretch of the dirt course facing the grandstand and infield. At the time, it was the largest ultra high-definition video board ever constructed. At the same time, 750 speakers were installed around the track.
