San Francisco -- Gap Inc. announced that its chairman and CEO, Glen Murphy, will step down, effective February 1, 2015. He will be succeeded by Art Peck, the president of the company’s growth, innovation and digital division.

Murphy and Peck have worked side-by-side for the better part of a decade as Gap dramatically improved its financial performance while expanding globally, the company said.

Cupertino, Calif. – Apple Inc. has reportedly hired Marcela Aguilar, senior global director of marketing communications for Gap Inc., to be its new director of global marketing communications, according to AdAge.

Instagram has become a mainstream social media tool for retailers. However, while most retailers limit their Instagram usage to maintaining an official page or encouraging customers to post photos with Instagram hashtags as part of promotional campaigns, some retailers are more forward-thinking in their Instagram approach.

Here are three retailers showing real insight in how they are leveraging Instagram to its fullest potential:

New York -- Costco Wholesale Corp. and L Brands Inc. were among the retailers that posted stronger-than-expected sales in August, fueled in many cases by back-to-school promotions.

Costco led the pack, reporting a 7% gain in August total same-store sales, ahead of views for a 4.9% gain. U.S. same-store sales, excluding the negative impacts from gasoline price deflation and foreign exchange, rose 7% as well. Top-performing categories at Costco included housewares, small appliances, apparel, fresh foods and food sundries.

Albany, N.Y. - Trans World Entertainment Corp., owner of the FYE music and video chain, named Michael Feurer as CEO. Feurer, who succeeds longtime Trans World leader and founder Robert J. Higgens, most recently served as CEO and president of Vanity Stores. Higgins announced in March he was retiring.

New York -- Gap is returning to television. The brand debuted four commercials that will air on TV, in cinema, in stores and online. Created by Academy Award-nominated director David Fincher, the films were created with Wieden+Kennedy New York as part of Gap's new marketing campaign, Dress Normal. The TV campaign launches in the United States and United Kingdom in the week of Sept. 1.

San Francisco -- Gap Inc. posted a better-than-expected quarterly profit and sales and raised its full-year profit forecast, helped by strong sales at Old Navy.

Net profit rose to $332 million in the second quarter ended Aug. 2, from $303 million a year ago.
