Starting in October of 2009, ESPN ran a series of documentaries that they called 30 for 30. I really enjoyed a large number of the films.
Twice in the last month, I have seen a reference to a second 30 for 30 series. In his week 17 NFL column, Bill Simmons predicts for 2012 that ESPN will launch a second 30 for 30 documentary series in October. At the 35:05 mark of his December 9 podcast with Michael Rapaport, Bill Simmons says that ESPN is starting the next 30 for 30 in October.
