Best Buy, an American multinational consumer electronics retailer, was originally founded by Richard M. Schulze and James Wheeler in 1966 as an audio specialty store called Sound of Music. It was famously rebranded in 1983, drawing inspiration from a highly successful "Tornado Sale" in 1981, which showcased a high-volume, low-price business model that would become central to its operations.

Headquartered in Richfield, Minnesota, Best Buy is recognized as the largest specialty retailer in the U.S. consumer electronics industry, with Corie Barry serving as CEO since June 2019. The company operates internationally in Canada and formerly had a presence in China and Mexico, also managing key subsidiaries such as Geek Squad and Magnolia Audio Video. Notably, in 1988, Best Buy revolutionized its retail approach by introducing "Concept II" stores, eliminating commissioned salespeople and providing more self-help product information to customers.
