Microsoft, Yahoo link instant message services - Tech News & Reviews - MSNBC.com: "Microsoft Corp. and Yahoo Inc. will make their instant-messaging programs work together, a partnership that could give the companies more power to compete against market leader America Online.
The Yahoo-Microsoft partnership, allowing users of the two services to exchange messages seamlessly, gives the companies nearly as many users combined as AOL has in total. The companies said in a statement Wednesday that they expect the service to start by June 2006."
