“Department stores in particular had difficulty surviving the onslaught of low-price competitors. Their inability to adapt to changing consumer tastes and the emergence of new retail channels that targeted specific market segments—the so-called category killers in hardware, toys, and furniture—deeply eroded their market share. While in the 1960s and 1970s most clothing was sold in full-service department stores, by 1990 such stores accounted for only 29 percent of sales.”
