Madison Square Garden, often abbreviated as MSG, has been the name of four arenas in New York City, United States. 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 as "The World's Most Famous Arena". The arena lends its name to the Madison Square Garden Network, a cable television network that broadcasts most sporting events that are held in the Garden.
