This week, Skate’s Art Market Research took a look at the state of competition among art businesses on Facebook, and revealed that brand recognition is not necessarily what one would expect on the social-networking service. The most-followed art companies, as the graph at right shows, run the gamut, with Saatchi, The Art Newspaper, and Shutterstock all appearing in the top five. (Kickstarter leads the way, but its business, admittedly, extends beyond funding art projects.) The report also shows that in four of the top five markets for Facebook users interested in art, Christie’s, Sotheby’s, and Gagosian are pretty much neck and neck, with Christie’s only far in front in the United States. (That result is particularly impressive for Gagosian: a private firm matching up well against a centuries-old behemoth like Sotheby’s, which has a $3.12 billion market capitalization.) Finally, a breakdown of art-sales listing platforms shows Artnet leading, followed by younger upstarts 1stdibs, Invaluable, and Artsy. The full report from Skate’s, which is owned by the same parent company as ARTnews, is available here.
