This year has shown that alot of lead ins well don't seem to lead anywhere. Networks are trying hard then ever to use lead ins with previews for the next show before showing an ad for next week and bars on the bottom highlighting whats to come yet look at some of the drop offs. Six-Degrees, Shark, One Tree Hill, the Nine, etc... some of them have massive drop offs, does this prove that lead-ins aren't that big of a factor?
