Microsoft retains Dentsu Aegis to global media buying account

Microsoft has retained Dentsu Aegis (DA) as its media buying agency globally.
After the review of its global media account in the US took place in the US, the company has decided to retain DA, which has held the contract since 2014.
It is believed the DA beat out both Wavemaker and Publicis Media, which were both in contention.
The win was announced within DA earlier today, The Drum understands but at the time of writing neither the network, nor Microsoft, commented when contacted.
