Englewood-based Liberty Media's recent announcement that it's purchasing the auto-racing franchise Formula One points to the growing popularity of the sport internationally, including a burgeoning audience in the United States.

Former Formula One driver Sam Posey, who now contributes to NBC, says the races are like no other with state-of-the-art cars, tracks with countless twists and turns, and avid fans.

Liberty Media, which also boasts interests in SiriusXM Radio and Charter Communications, will pay $4.4 billion for the company and will retain the enigmatic 85-year-old British magnate Bernie Ecclestone as chief executive officer. 

Posey spoke with Colorado Matters host Ryan Warner about the history of Formula One and why he fell in love with the sport.
