Since 2009, ESPN and its sister networks have aired a series of sports documentary films titled 30 for 30. The idea was initially conceived by sports critic Bill Simmons and producer Connor Schell as 30 one-hour films by 30 filmmakers to celebrate ESPNs 30th anniversary. But 30 isnt a big enough number to cover the many incredible moments that have popped up in the world of sports, so the ball has continued rolling ever since.
