Weak Signal's description 
Traditionally, innovations found their way from developed to emerging markets in the form of less-sophisticated products at lower prices. The numbers of examples that work the other way around are increasing. It is more and more the case that innovation "trickles up" from emerging to developed nations. GE Chairman Jeffrey calls this tendency “reverse innovation”. Which means to say that since developing and emerging countries have become big and sophisticated markets a growing number of Western companies make use of cheap R&D and low-cost manufacturing in these regions and start innovating locally for the domestic market. Afterwards they introduce the innovations to their Western home markets.
