Deletion of Black cube art museum

Comment: it appears to be a |Neologism and not a common term I've ever come across before in the art world. I can't find any evidence online (unlike "White cube gallery|White Cube") that convinces me otherwise. None of the galleries listed in the article describe themselves as "black cube" galleries
