About this time the Seminole cattle industry began which has made good money, and allowed them to expand into other areas. Since the 1930s they have gotten into the sale of duty-free tobacco, resort tourism. In 2006 they bought the Hard Rock Café chain of restaurants. In 1979 Seminoles opened the first casino on Indian land, a practice that has become a multibillion-dollar industry for tribes around the nation. Income from the casinos in recent years funded citrus groves, ecotourism and sugarcane fields.
