Amazon has completed its anticipated media review, splitting up the global remit between Omnicom Media Group and WPP, with the latter to handle the tech giant's media account in the APAC and EMEA regions. OMG, meanwhile, will handle work in the Americas.

As first reported by Adweek, the account review process took more than six months from end-to-end, and was supported by a third-party review by Mediasense.

"This decision was made after a careful and extensive review process," Amazon spokesperson Margaret Callahan said in a statement shared with Mi3. "We investigated each agency's marketplace expertise, media planning experience at all levels, media pricing, measurement abilities, and account management in all geographic regions."

The account was previously held by IPG Mediabrands, which had won the account in 2013 and successfully defended it four years later.

"We appreciate the discussions with of all the world-class agencies we met during our search," Callahan continued. "We particularly want to thank IPG, who has been a fantastic partner over the last 10+ years, and we're grateful for all their work and continued partnership for the other significant areas of our advertising business, including AWS, Amazon Ads, and Amazon Business."
