"Trickle-up innovation"

"This month, General Electric's (GE) health-care division will begin marketing a first-of-its-kind electrocardiograph machine in the U.S. Although packed with the latest technology, the battery-powered device weighs just six pounds, half as much as the smallest ECG machine currently for sale. It will retail for a mere $2,500, an 80% markdown from products with similar capabilities. But what really distinguishes the MAC 800 is its lineage. The machine is basically the same field model that GE Healthcare developed for doctors in India and China in 2008.

The process turns conventional product development on its head. Over the years, multinationals have prospered by turning out premium-priced products for the world's affluent. Rather than also designing products for poorer people elsewhere, many businesses found they could simply pass yesteryear's models down, as if they were unloading fleets of used cars. Lately, big companies such as Microsoft, Nokia, and Procter & Gamble are discovering that they can profit by targeting the world's masses first. And they can score again by selling these low-priced products elsewhere."
