The company originally focused on horse racing and has since expanded into the gaming industry with the acquisition of Parx Casino. Today, Parx Casino is owned and operated by Greenwood Racing Inc., a company that was founded in 1989 by British businessman Bob Green. Notable events in Parx Casino’s history include the opening of a poker room in 2003 and the addition of live table games in 2010. The following year, the track was renamed Philadelphia Park and became the first racetrack in Pennsylvania to offer casino gaming. In 1990, the track underwent a major renovation, which included the addition of slot machines. The track was owned by the Philadelphia Park Corporation and offered thoroughbred horse racing to the public. Parx Casino’s early years were marked by its humble beginnings as Keystone Racetrack, which opened in 1974. The story of how Parx Casino came to be known as such is an interesting one, with a rich history that spans back several decades.
