2. Early Life and Career Beginnings
Born in Pittsburgh, Pennsylvania, Cuban displayed an affinity for business at age 12, selling garbage bags door-to-door to pay for a pair of expensive sneakers. After graduating from Indiana University in 1980, he moved to Dallas, where he was fired from a software sales job for closing a deal instead of cleaning the shop. This motivated him to found MicroSolutions, a computer consulting service he sold to CompuServe in 1990 for $6 million.
In 1995, he and Todd Wagner co-founded AudioNet (later Broadcast.com) to stream Indiana basketball games online. They sold the company to Yahoo! in 1999 for $5.7 billion. Cuban famously protected his fortune by hedging his Yahoo! stock before the dot-com bubble burst, a move often cited as one of the greatest trades in history.
