Sony Mobile called the pitch in March with a brief that the successful agency would produce work to supplement its brand and product campaigns.
The company’s procurement team handled the review in-house. A&E/DDB’s specialist content division Cain & Abel, which launched last November, will be responsible for the account.
In a statement, Sony Mobile said: "Following the pitch process which was reported in March, Sony Mobile has extended Adam & Eve/DDB's remit on the business by appointing its content division, Cain & Abel to work across various product communications projects."
A&E/DDB won the global Sony Mobile account in May 2013. Sony Mobile previously worked with McCann London.
