WPP will spend $70m wth Snapchat in 2016

"On behalf of its clients, ad giant WPP is spending about $70 million (£56 million) with Snapchat, the company's chief executive Martin Sorrell said on Tuesday at the UBS Media and Communications Conference, The Wall Street Journal reports.
The figure is just a pinch of the money it spends on other digital platforms — in October Sorrell said WPP will spend $5 billion (£4 billion) with Google this year, up from $4 billion (£3.2 billion) in 2015. That year the company spent $1 billion (£800 million) with Facebook."
