Those productions that are battling on are generally offering huge discounts on tickets, or even giving them away free.
Disney is offering a "Kids Go Free!" deal for its three family musicals – The Lion King, Mary Poppins and The Little Mermaid – for three months after January.
Although Billy Elliot is bucking the trend and doing well, big budget productions are particularly vulnerable.
A $4.5 million revival of Godspell has been scrapped while a lavish $16 million musical version of A Tale Of Two Cities closed in November, just two months after it opened.
