Sotheby's shares a rivalry with Christie's for the position of the world's preeminent fine art auctioneer, a title of much subjectivity. In August 2004, Sotheby's introduced an online system – MySotheby's – allowing clients to track lots and create "wishlists" that could be automatically updated as new works became available. Sotheby's also created the BIDnow service, which allows bidders to bid real-time online while watching the broadcast auctions, with the exception of Wine auctions. LiveBid is Sotheby's online bidding system exclusively for wine auctions. In the meantime, income from classic auctioneering has fallen, as Sotheby's reported a decrease of 42% in net income in the first half of 2012.
