News Summary: Google expands into product delivery

DELIVERING THE GOODS: Google hopes to make online shopping a more appealing option by offering same-day delivery of groceries and other products ordered on the Internet. The express service announced Thursday initially is being tested among a small group of consumers living in the San Francisco area.

WHO'S ON BOARD: A variety of neighborhood, regional and national retailers such as Target Inc. and Walgreen Co. have enlisted in Google Shopping Express.

POTENTIAL PAYOFF: Google is always looking for ways to increase people's reliance on the Internet so it will have more opportunities to show the online ads that generate most of its revenue.
