In 1983, with seven stores and $10 million in annual sales, Sound of Music was renamed Best Buy Company, Inc. The company also expanded its product offerings to include home appliances and VCRs, in an attempt to expand beyond its then-core customer base of 15- to 18-year-old males. Later that year, Best Buy opened its first superstore in Burnsville, Minnesota. The Burnsville location featured a high-volume, low-price business model, which was borrowed partially from Schulze's successful Tornado Sale in 1981. In its first year, the Burnsville store out-performed all other Best Buy stores combined.
