In July, eBay announced a partnership with noted auction house Sotheby’s to help bring its inventory of art, antiques and collectibles online via a new live auction format with real-time bidding. At the time, eBay said Sotheby’s was the “anchor tenant” to trial this new format on eBay.com. Today, the company is expanding on these earlier efforts with a number of other well-known auction houses, including Doyle New York, Freeman’s, Garth’s Auctions and Swann Auction Galleries, which will all now feature art auctions via a new section on eBay’s website.
