“For most of its history, Broadway was like a train station. Shows came and went; some big hits would stick around for a few years, then leave before too long. But things have changed, or to be precise, stopped changing. September is traditionally the time when the marquees light up with new titles, productions fresh from the road tryout or from a successful run at a smaller theater. This year, however, 10 of the shows on Broadway have played more than 1,000 performances, 7 of them more than 2,000.”
