I want to know the answer to the following question:
When did the inaugural TCM Classic Film Festival take place?
All the background I'm provided with is that "Hosted by Robert Osborne, the four-day long annual festival celebrates Hollywood and its movies, and features celebrity appearances, special events, and screenings of around 50 classic movies including several newly restored by the Film Foundation, an organization devoted to preserving Hollywood's classic film legacy.". Is that enough to answer the question?
