International Game Technology (IGT) has operated since 1975 and is the world's largest gaming technology company by revenue — designing, manufacturing, and distributing gaming machines to over 100 countries. IGT created the Fortune Coin video slot in 1975 (the world's first commercial video slot), Double Diamond in 1989, and Wheel of Fortune in 1996 — now the best-selling US casino slot machine in history. The company listed on NYSE as IGT following its 2015 merger with GTECH Holdings. IGT's online division produces social casino content through DoubleDown Casino and licensed versions of its land-based titles for regulated online markets. IGT's Jackpot Party Casino app — operated via subsidiary SciPlay (NASDAQ: SCPL) — is among the world's most downloaded social casino games.
