January has long been the month for Broadway to bring out its dead. Having wrung the final drops of revenue from New York City’s holiday tourism boom, productions with limited runs or falling sales wisely close up shop, making room for the onslaught of spring productions in the process.

From a strictly commercial point of view, the numbers have never been better. The Great White Way just had its greatest year on record, grossing more than $1 billion, up from $940m the previous season and $588m ten years ago.
