Last spring Nick Horbaczewski didn't have a clue what drone racing was. Now he's the CEO and founder of the Drone Racing League (DRL), with investors that include Miami Dolphins owner Stephen Ross. Since officially launching in January, DRL has made it clear that it's vying to be the Nascar of drones, offering marketers and media partners a professional alternative to the burgeoning amateur sport. "People see the potential of this as a sport that can excite and engage a millennial audience," said Horbaczewski. "It's not only its technology roots and its comparability to esports, it's also the format of the race."
