Microsoft will sell a version of its Xbox 360 with a 120-gigabyte hard drive and a souped up high-definition video connection, in a bid to broaden the appeal of its popular console beyond video games.

Earlier versions of Xbox 360 came with 20 gigabytes of storage. But that filled up too quickly with movies, TV shows and games from the Xbox Live Marketplace online store, said Peter Moore, a corporate vice president in Microsoft's Interactive Entertainment group.
