Conan’s last turn as host of The Tonight Show garnered a 4.8 rating with adults 18-49 in the 25 local markets with Nielsen people meters.
If those numbers hold up, not only is it a series high with adults 18-49 it’s 85% higher than the previous series high set Thursday night (2.6 rating), it’s over 40 percent better than the 3.4 rating with adults 18-49 Jay Leno got in his not-so-final Tonight Show after all on May 29. Leno’s not-so-final episode also scored nearly 12 million viewers. Viewer numbers for last night’s episode won’t be available until late next week.
Not only was it better than all the late night and primetime competition on Friday — not really a huge feat with most networks broadcasting the Hope for Haiti Now benefit between 8p-10p, it was also a better 18-49 rating than any show got on Thursday night.
Update: the previous series high, at least in final numbers (again the numbers above are preliminary) was a 3.8 rating with adults 18-49 for Conan’s Tonight Show premiere last June.
