For those constantly asking when these Jay vs. last year's posts will end, just 4 weeks to go. Plan your post-February whining now! Although after that date I plan to start a new chart with current year late night ratings only to gauge reader interest.
The chart shows the late night adults 18-49 weekly average ratings for 2009 and 2010.
New and improved with Conan TBS ratings!
