From the Economist's recent report on innovation in emerging markets here, the article "Easier said than done" showcases pyramid-straddling - the concept where a brand is able to win across all socio-economic market segments.
"... the masters of pyramid-straddling are mobile-handset makers. Nokia produces phones for every market, from rural models designed to cope with monsoons to fashion accessories that will look cool in a Shanghai nightclub. The cheap phones are sold through a vast network of local outlets, such as mom-and-pop stores and rural markets, and the upmarket models through shops in fashionable city centres. The aim is to create a brand that is at once universal and aspirational."
