That (i.e., the title of this post) was my comment when someone I know showed me the reprint edition of the first issue of the New York Rev. of Books, which the journal is offering for sale as part of its 50th anniv. celebration: see here. Also, there is a free two-day conference in Oxford later this month in connection with the anniv.: see here.
For a number of years, for most of the '80s and into the early '90s as I recall, I subscribed to the NYRB. Though I eventually stopped subscribing, I think it's clear that the journal has had a good run.
