There are only a few things left to say about NBC's historic mismanagement of the Leno/O'Brien disaster, but they are important nonetheless. The top thing as I see it is that this isn't over yet. Leno is going to have to work hard to rebuild the lost audience for The Tonight Show after the Olympics, because those people aren't going to come back on their own.
Not all of them, and probably not a majority of them.
Sometimes I wonder if these studios are intentionally trying to fail.
What else could explain this? Paranormal Activity succeeded despite the studio system. It was shot as an indy, got enough attention to get a couple of million to reshoot the film with more resources (because that always works out for the better), then the original version was released into theaters when it turned out better than the more expensive reshoot did.
