AT&T's Yellowpages.com to list on Microsoft sites

NEW YORK (Reuters) - AT&T Inc said on Monday its Yellowpages.com directory will distribute its listings on Microsoft Corp's local search sites, replacing Idearc Inc's Superpages.com service.

AT&T shares firmed 0.66 percent to $35.26. Shares of Idearc, which operates Superpages, fell 11.26 percent $4.02 by late morning trade.

The agreement is due to take effect in early April, AT&T said. Terms of the deal were not disclosed.

AT&T said on Monday it expects revenues from Yellowpages.com and content advertising, including ads on its mobile phones as well as its U-Verse high-speed Internet and video services, to exceed $1.5 billion by 2010, up from around $600 million in 2007.
