E-commerce in the grocery segment may become “a bigger deal faster than people realize,” Bryan Gildenberg, chief knowledge officer, Kantar Retail, tells SN in a the second in a series of video interviews. Wal-Mart has honed its e-commerce skills competing in the U.K., and could expand the “online ordering/non-home fulfillment” model in the U.S., he says. Wal-Mart’s annual shareholder meeting took place Friday, June 1. SN will provide in-depth analysis in its June 25 issue. SN analyzed Wal-Mart’s impact on the supermarket industry during its first 50 years  earlier this year.
