This stability has two very important implications. The first is that those who are clear brand leaders are especially well placed in relation to their competitors and should want to further the inertia which lies behind that stable position. This, however, still demands a continuing pattern of minor changes to keep up with the marginal changes in consumer taste (which may be minor to the theorist but will still be crucial in terms of those consumers' purchasing patterns as markets do not favor the over-complacent). These minor investments are a small price to pay for the long term profits which brand leaders usually enjoy.
