For well over a year now, the digital advertising and publishing industries have grappled with the growing power of Google and Facebook, which suck up 98% of every new ad dollar spent online, according to some estimates. With so much growth and power concentrated in just two companies, publishers worry about the viability of their ad businesses, while advertisers bemoan their loss of leverage around ad buys.
Deeply unsettled by the idea of a Google-Facebook duopoly, both groups have done what they can to defend against it. But so far, nothing they’ve done seems to have worked.
It seems so obvious to say that two companies controlling this much of the online advertising market is bad.
