Walmart, giant American retailer, will acquire Kosmix, which will help it increase their e-commerce & social media presence. Walmart recently collaborated with Justin Beiber which helped it increase twitter folowers. With social media increasingly playing a greater role, this would help it increase online visibility. Amazon.com, recently acquired Diapers.com and Soap.com, which will help it move more into the B2C segment. Eventhough it is a giant retailer, in the online space, its sales are much smaller compared to amazon & others. Retailers are offering special discounts, group discounts & others in a bid to increase the online sales. This will also help it to move to the mobile space.
