America Online has launched InStore, an online comparison-shopping site (www.in-store.com). With its subscriber base dwindling, the site is part of the Dulles-based firm's strategy of reaching beyond its members to profit from ads and merchandise sold to other Internet users.

"InStore will capitalize on the opportunity to use the increasing power of search, the speed and rich media capabilities of broadband and improved personalization tools to take the experience to the next level," Michael J. Kelly, president of AOL Media Networks, said in a prepared statement.

* Coventry Health Care of Bethesda said Allen F. Wise, its president and chief executive, will step down Jan. 1. Coventry's board named its executive vice president and chief financial officer, Dale B. Wolf, to succeed Wise.

Wolf, who worked for Wise for the past eight years, said he has no plans to change course. "We've sort of developed a strategy over a period of years together and we're going to keep on doing it," he said.
