Launched last month, the CMA’s market study sets out to assess three broad areas:

• To what extent online platforms have market power in user-facing markets, and what impact this has on consumers

• Whether consumers are able and willing to control how data about them is used and collected by online platforms

• Whether competition in the digital advertising market may be distorted by any market power held by platforms

As the industry body for digital advertising, IAB UK has submitted a response to the CMA’s invitation for comments. You can view or download our response here.
