Madison Square Garden, often abbreviated as MSG, known colloquially simply as The Garden, has been the name of four arenas in New York City, United States. It is ... the name of the entity which owns the arena and several of the professional sports franchises which play there. There have been four incarnations of the arena. The first two were located at Madison Square, thus the name. Subsequently a new 20,000-seat Garden was built at 50th Street and 8th Avenue, and the current Garden is at 7th Avenue between 31st and 33rd Streets, situated on top of Pennsylvania Station. The present arena is informally known to some by its advertising slogan, "The World's Most Famous Arena".
