Google & Facebook 'get 75% of all new online ad spending'

"The bulk of spending by brands on digital advertising is going to Google and Facebook. Combined, they accounted for 75 per cent of all new online ad spending in 2015, according to the Internet Trends report published this month by Mary Meeker of Kleiner Perkins Caufield & Byers, the US venture capital fund. In the US, 85 cents of every new dollar spent on digital went to the two companies in the first quarter of 2016.
This matters because digital is fast becoming advertising’s biggest source of revenue. It will eclipse television in the US next year , according to eMarketer, the research firm, with the lion’s share likely to go to the digital duopoly of Facebook and Google. Executives in Cannes put a brave face on what this might mean for their industry but the consequences of two companies becoming the gatekeepers for most digital advertising are profound."
