Based on last night’s ratings, viewers can’t get enough of the soon-to-be "Tonight Show Without Conan O’Brien."
O’Brien’s big city tune-in increased again Wednesday, with "Tonight" notching a 1.8 rating among adults 18-49, according to metered market overnight numbers from the 25 big cities where Nielsen measures such data. That’s up from Tuesday’s 1.7 rating — and nearly double the 1.0 earned by CBS’s "Late Show with David Letterman" (Dave was also up, from a 0.9).
The "Tonight" number is particularly impressive since NBC’s primetime performance is best these days on Tuesdays. And yet O’Brien did better even though the network supplied less of a lead-in on Wednesday.
