By 1922, Dole had managed to convince his family's network in Hawaii and in Boston to arrange for a sizable capital investment fund with which he purchased the island of Lānai and developed it as a vast pineapple plantation. It became the largest plantation in the world with over 20,000 acres (8,100 ha) devoted exclusively to growing pineapple. Utilizing large mechanized production and importing large numbers of foreign workers who were paid at indentured servitude levels, Dole managed to reduce the price of his pineapples to such a level that it drove every other producer out of the business which didn't fall into line with his scheme. With this vast pineapple cultivation at the company's disposal, throughout the 20th century, Lānai produced over seventy-five percent of the world's pineapple crop, thereby dominating the market, and in turn, the place acquired the nickname of Pineapple Island. Dole also purchased land on the island of Maui. The largest competitors in the production of pineapple in Hawaii were Maui based affiliates of Alexander & Baldwin.
