At the start of the 1980s, Unilever is the world's 26th largest business, with interests including plastics, packaging, tropical plantations and a shipping line, as well as a wide range of foods, home and personal care products. Early in the decade, in a bold change of strategy, we decide to refocus on core product areas with strong markets and equally strong growth potential. The necessary rationalisation leads to large acquisitions and equally large divestments. But by 1989 the resulting growth of core businesses is clear.
