Bottles and cans of Pepsi soda are seen on display in a store. This week Pepsi announced the details of its new year-long integrated marketing campaign with Twitter. - 

In an effort to revive their brand image and win back market share from Coke, Pepsi is launching a new, hip partnership with Twitter.
