When Black Friday comes, Yahoo! ( YHOO) is hoping to see green. Though the malls will hardly be empty this holiday season, the Web is emerging as a huge shopping destination. Online sales are rising faster than overall retail sales, and competition is flourishing both online and off. With consumers using the Internet to find bargains, comparison shop and learn about products, the battle is joined for virtual shopping supremacy. At the center of the fray is Yahoo! Shopping. The site, at shopping.yahoo.com , is one of many that Yahoo! counts on to retain its status as the most visited site on the Internet. Online outfits ranging from Google ( GOOG) and Microsoft's ( MSFT) MSN have rival shopping sites, and of course there are other big online shopping plays like Amazon.com ( AMZN) and Overstock.com ( OSTK). Rob Solomon, the general manager of Yahoo! Shopping, sat down with TheStreet.com to discuss his strategy for the holiday season.
