There will be a lot of NBC late-night lasts and highs over the next few days as Jay Leno wraps his second and likely final turn on The Tonight Show and Jimmy Fallon prepares to succeed him. Last night was the final Friday edition of The Tonight Show With Jay Leno, which bows out February 6, with both Tonight and Late Night posting big ratings. Despite lower viewership levels on Friday, Tonight Show scored a 3.9 in metered-market households, a season high and its best result in 15 months; since Wednesday, October 24, 2012 when President Obama was a guest (4.0). It was the highest Friday Tonight rating since July 27, 2012, the night of the London Olympics Opening Ceremony (4.0). Leno boosted his successor, with Late Night With Jimmy Fallon logging a 2.2 in households, the show’s highest rating for any night of the week in four years, since February 12, 2010, the night of the Vancouver Olympics Opening Ceremony (2.5).
