As the economy slows and many big retailers run out of space to open new stores, they are dusting off a tried-and-true strategy: Sell more products in the stores you have. "A lot of retailers are looking at 'How can I sell more things to the people already in my store,'" says Mary Brett Whitfield, analyst at TNS Retail Forward.

Sony is gambling that after years of upheaval caused by digital technology, the music industry will regain its footing. It is buying Bertelsmann's 50% stake in Sony BMG Music Entertainment for $900 million, ending a four-year partnership that generated much dissonance. Bertelsmann retains rights to 200 European artists, giving it a toehold in a business it once dominated.

Its roster of entertainers includes Alicia Keys, Avril Lavigne and Justin Timberlake. "The advent of the cellphone as a conveyor …

After the film's mediocre theatrical run, two of the film's unknowns -- Blake Lively and America Ferrera -- emerged as major television stars. Marketing for the new movie capitalizes on the girls' newfound fame. The sequel's poster features a close-up of the girls' four faces, largely ignoring the iconic traveling pair of pants that form the film's back story. "The jeans are still the glue of the film," says Sue Kroll, …

MillerCoors is sending Miller High Life's delivery-guy mascot to stump for the "High Life Common Sense Party" in 12 markets and on Internet sites such as Facebook and YouTube. Campaign stops that are an extension of TV ads for the brew are set for Major League Baseball and college football games. The TV spots show the driver confiscating High Life from French bistros, gourmet grocers, luxury boxes and other too-chic locations at odds with the brand's blue-collar ethic. The driver has also been making appearances at sporting events since last summer. The driver will continue to rail against all …

Rhapsody music service, which offers access to over five million songs for a monthly fee, recently opened an MP3 store and began a new alliance with Verizon Wireless that puts its subscription music in front of nearly 70 million customers.
