The full study is on OHIM's website. A summary is also available.
The report identified premium brands belonging to 46% of the top 100 companies by global ad spend, and found that 70% of ads collected for named brands were for just 97 brands.
Moreover, 54% of ads collected were in high-risk sectors (malware, fraud and adult) and just 10 out of 232 intermediaries placed 91% of all high-risk ads collected.
Based on this finding, the report suggests that the biggest intermediaries have a significant role to play in tackling the problem.
