Amazon Takes on Disney’s Superheroes in Online Fight

Amazon.com is taking on Walt Disney Co. and its superheroes in a quest to gain more control over pricing online. Amazon blocked pre-orders of Disney's summer hit movie "Captain America: The Winter Soldier" and other titles in disk form, repeating a tactic used in recent disputes with book publisher Hachette and film studio Warner Bros. The move signals that Amazon, the world's largest web retailer, is increasingly willing to keep certain items from consumers to put pressure on its vendors.
