A few weeks ago, Belgium’s data protection authority released a decision that is likely to fundamentally alter Europe’s online advertising industry if it becomes enforceable once the legal process has fully played out.

In its 127-page decision, the embattled data protection authority found a consent framework for online advertising developed by IAB Europe, the European trade association of the digital and interactive marketing industry, in violation of GDPR. Stating that its decision would “restore order” in the online advertising industry, the Belgian regulator – which has been roiled by infighting for months – issued the industry body a fine of €250,000 and gave it two months to address its concerns.
