B.S., tennessee tech ’81 before becoming a videogame entrepreneur, Yarbrough was a college student playing a lot of foosball, interning at nasa and studying to earn an engineering degree at tennessee tech. his interest in gaming as a business started when he noticed how much he was earning from loaning his foosball table to a local saloon. (the owner agreed to let him keep it there and split the revenues with him.) this led him to eventually create his casino-game business video gaming technologies in 1991; it became a popular supplier to native american casinos. Yarbrough sold the company to the australian firm aristocrat leisure for $1.28 billion in 2014.
