Walmart is integrating its video streaming service, Vudu, with its Walmart.com website. Walmart acquired the cloud-based movie service in 2010. The service lets customers buy or rent movies to be streamed directly from Walmart.com or Vudu.com or from one of 300 Vudu-enabled devices including select HDTVs, Blu-ray players and the PlayStation 3. Walmart.com shoppers will have the option to select movies on discs or in digital formats on the same page.
