The Excite.com Web site wonÂ’t be affected by the current brouhaha. InfoSpace Inc., a Web-site operator in Bellevue, Wash., has been running the Excite site, in partnership with iWon Inc., as part of its purchase last week of some of Excite At HomeÂ’s media assets, including domain names, trademarks and user traffic associated with the Excite.com Web site. In terminating the asset offer, AT&T maintained that Excite, Redwood City, Calif., had significantly violated the agreement in numerous ways, including the termination of AT&TÂ’s service.
