In the post-war years, Genoa played a pivotal role in the Italian economic miracle, as the third corner of the so-called Industrial Triangle, formed with the manufacturing hubs of Milan and Turin. Since 1962, the Genoa International Boat Show has evolved into one of the largest annual events in Genoa. The city became an important industrial centre, giving rise to manufacturers of diving equipment (Cressi-Sub, Mares, and Techisub SpA), ferries (GNV and Home Lines, and the "OSN-Orizzonti Sistemi Navali"), oil production ("IP-Italiana Petroli"), textiles (SLAM), food services ("Elah Dufour" and "Sogegross"), construction ("FISIA-Italimpianti"), and, for a time, nuclear reactors (NIRA, which closed after the Chernobyl disaster).
