Things could not have gone any better for NBC chairman Bob Greenblatt the past few weeks. Last month, he was in New York to present the network’s fall schedule where he touted his network’s first No. 1 finish among adults 18-49 in a decade. Last night, he was back in the Big Apple to celebrate his musical, A Gentleman’s Guide To Love & Murder, sweeping the Tony Awards with four wins, including best musical. As our Pete Hammond noted in his Tony Awards analysis, the top NBC programming executive is among the producers of the top winner last night. Greenblatt is a well known theater lover who previously produced the Broadway production of 9 To 5. Since taking the reins of NBC, he put on the air drama series Smash, about the mounting of a Broadway musical, and The Sound Of Music, a live staging of the classic musical. The latter drew massive ratings last December, launching a holiday franchise for NBC, with a live production of Peter Pan next.
