The Art Newspaper made a surprising discovery analyzing their museum attendance figures. It turns out five major galleries have a commanding position representing the artists who get solo shows. Is it the artists? the galleries? the roving rock-star curators?

Nearly one-third of the major solo exhibitions held in US museums between 2007 and 2013 featured artists represented by just five galleries, according to research conducted by The Art Newspaper. We analysed nearly 600 exhibitions submitted by 68 museums for our annual attendance-figures survey and found that 30% of prominent solo shows featured artists represented by Gagosian Gallery, Pace, Marian Goodman Gallery, David Zwirner and Hauser & Wirth
