Changes in technologies have always been linked to product development. New home technologies like washing machines and refrigerators created markets for new products like laundry detergent and frozen food, which in turn required new packages. New manufacturing technologies further revolutionized certain products, changing the ways they could be packaged, purchased, and consumed.
These innovations created both opportunities and pressures for manufacturers. Innovations challenged producers to create new products and packages, and to market their goods in creative ways. New products and novel packages required their makers to convince consumers that these new things would improve their lives.
