Here's Jay Leno on the defensive. It's kind of an odd interview. The questioner tries eighty different ways to get Jay to admit to panic and worry about his situation, and he barely bites. I think Leno's right that if his 10 PM show goes away, that will not lead to NBC programming five hours of expensive dramas that will hire everyone who wishes they were on a series at that hour…just to more "reality" programs and Dateline. It will also not probably lead to five hit shows in that Monday-Friday slot.
Then again, you all know the joke about rearranging deck chairs on the Titanic. Jay isn't even rearranging furniture; he's just saying, "Hey, I've been on sinking ships before and I'm good at it." What I'm hearing out of NBC is that everyone's scurrying to come up with a Plan B and nobody has one yet.
