Advertising mogul Martin Sorrell told CNBC on Wednesday his company is poised to increase its investment in Facebook to "well over" $2 billion this year.
WPP, the world's largest advertising group, will keep Google as its top media investment in 2017. However, Sorrell suggested the firm's client portfolio could be set to see Facebook move ahead of Rupert Murdoch's News Corporation in second place.
"Google ranks number one in terms of the destinations of our media investments. Facebook ranks third (but) may this year actually become second," the CEO of WPP told CNBC on Wednesday morning.
Sorrell explained WPP's investment in Google amounted to approximately $6 billion, while the amount put in to Mark Zuckerberg's social media network is set to increase to more than $2 billion in 2017, up from $1.7 billion in 2016. Google's parent Alphabet has a market capitalization of about $646 billion and Facebook $492 billion.
