Winterland Ballroom was an ice skating rink and music venue in San Francisco, California, United States. The arena was located at the corner of Post Street and Steiner Street. It was converted for exclusive use as a music venue in 1971 by concert promoter Bill Graham and became a popular performance location for many rock acts. Graham later formed a merchandising company called Winterland Productions, which sold concert shirts, memorabilia, and official sports team merchandise.
