Founded in 1744 as a book auctioneer, Sotheby's has become the first international auction house to expand from London to New York, and the first to conduct sales in Hong Kong. Selling some of the world's most valuable fine jewellery, decorative arts and other precious objects, all of Sotheby's presale exhibitions and auctions are free and open to the public. Sotheby's has also created the BIDnow program, which allows visitors to view all auctions live online as well as enabling them to place bids from anywhere in the world.
