1975–1990

IGT was founded as A-1 Supply by William "Si" Redd in 1975.^[2] It changed its name to Sircoma in 1978, and then to International Game Technology in 1981.^[2] The company went public in 1981.^[3] A deciding factor in IGT's decision to go public occurred a few years earlier with the success of its video poker machine gaming product.^[4] This product served as a "foot in the door" for the company into several gaming arenas.

In 1984, IGT acquired Electronic Data Technologies making the company one of the first to use the computerized player tracking concept and later instrumental in the proliferation of "frequent-player rewards" programs, which remain popular in casinos to this day. This initial system gave casinos a new marketing tool in player management. Over time, the tracking system evolved into the company's IGT Advantage^[5] and sbX^[6] systems.

After IGT's initial public offering and listing on NASDAQ, the company debuted many new technologies over several years. A number of products resulted from this process including the S-Slot, which marked the company's entrance into the microprocessor-driven spinning-reel slot market, and the Player's Edge video poker machine. In addition, the company introduced the Nevada Megabucks slot machine, the world's first wide-area progressive slot machine system. With an initial base top jackpot of $1 million, this new game allowed for million-dollar player payouts for casinos on the system. During this time, IGT also established an Australian office to focus on the country's club market.

2013–present

In January 2013, IGT filed its preliminary proxy materials and indicated that it had received a Notice of Intent to Nominate four director candidates for election to the IGT Board at the Company's 2013 Annual Meeting through The Ader Group, run by Jason Ader. The intent of the notice was to inform IGT and its shareholders of a proxy battle that was going to take place, and that the Ader group's nominees include the slot-machine maker's former chief executive Charles Mathewson, and Jason Ader himself.^[35][36]

Following the initial release by IGT, The Ader Group issued a statement claiming that IGT relayed inaccurate information concerning Jason Ader and the Ader Group's proxy fight.^[37] The initial filing with the Securities and Exchange Commission by IGT suggested that Ader's group seeks election to the board, as Ader and Mathewson control 3 percent of IGT, (8.05 million shares), and they are seeking additional proxies for the company's 2013 annual shareholder meeting to put Mathewson back on the board IGT.^[37][38] IGT maintained its original statement.^[37]

On January 11, 2013, the Ader Group filed its proxy indicating that it had nominated three people for the IGT board, of which Jason Ader was not one of the candidates. The proxy statement charged IGT has lost value as a result of the decisions and direction of its leadership.^[39]
