IMUnified

IMUnified, formed in 2000, is a coalition of companies that intend to develop open standards for instant messaging (IM). The founding members are AT&T, Excite@Home, iCAST, Microsoft, Odigo, Phone.com, Prodigy, Tribal Voice and Yahoo!. Notably absent from the list of members is AOL, who was not invited to join the coalition. Some analysts believe the goal of the coalition was to try to force AOL toward a more open IM standard.
