In 1989, the company introduced a new store concept dubbed "Concept II". Concept II replaced dimly lit industrial-style stores with brighter and more fashionably fixtured stores. Stores also began placing all stock on the sales floor rather than in a stock room, had fewer salespersons and provided more self-help product information for its customers. Best Buy also did away with commissioned salespeople. The commission-free sales environment "created a more relaxed shopping environment free of the high-pressure sales tactics used in other stores," but was unpopular with salespersons and suppliers. Some suppliers, such as Maytag, Whirlpool, and Sony, were upset that salespeople would no longer be pushing their products and stopped selling in Best Buy stores altogether. The suppliers returned after Best Buy's sales and revenue grew following the roll-out of Concept II.
