In March 1998, both houses announced they would have significant presences on the Web in 1999. As of this writing only Sotheby's has any significant web presence. Some dealers fewer and fewer - continue to use magazine print. The problem with print is that the manufacturing costs and postage continue to escalate, while circulations stagnate. Moreover, most magazines circulate in a specific country.
International distribution is virtually unheard of.
There are also a number of other web sites . . . These sites operate on the consignment model, similar to an auctioneer. In effect they take the dealer out of the transaction. I see a lot of great galleries on your site. Remember, most Internet users are not looking for a specific gallery.
