In​ 2010, domino's launched a new advertising campaign admitting that its pizzas had not tasted very​ good, but claiming that they had developed a new recipe that greatly improved the taste. if​ domino's succeeded in convincing consumers that its pizza was significantly better than competing​ pizzas, would its demand curve become flatter or​ steeper? when a product becomes lessless differentiated from other​ products, its demand curve becomes ▼ steeper flatter . this happens because the slope of the demand curve reflects buyer responsiveness to a price​ change, which is determined in part by the availability of substitutes.​ thus, when a product becomes lessless differentiated from other​ products, buyers perceive it as having ▼ fewer more good​ substitutes, and this altered perception induces buyers to be ▼ less more responsive to price.
