Similarly there are some variations in the sorts of markets served by establishments of different vintages. The branch plants established during the 1960s and 1970s are those which are often considered, in the literature, to be those which have been most rationalised and most oriented towards mass markets. In Table 7.2 the data suggest that there is no real evidence of this being the case for multinational manufacturing establishments in Wales. Indeed, if anything, those operations established since 1990 appear to be most oriented towards mass markets. Whilst the older operations appear to be most orientated towards serving niche markets.
