On this week's episode of The MadTech Podcast, ExchangeWire's Ciaran O'Kane and Rachel Smith are joined by Jonas Jaanimagi, technology lead, IAB Australia, to discuss the latest news in ad tech and martech.

On this week's episode:
- The ICO Ad Tech Update report has openly criticised RTB and questions its legality in terms of data protection compliance. Will the ICO bring a ruling against ad tech companies operating in the UK in six month's time? Is there a comparable situation in Australia?
- A report from Juniper Research estimates that global digital ad spend is set to reach USD$520bn (£409.9bn) by 2023, with Amazon taking an 8% global market share compared to just 3% today. Where is the budget shifting to Amazon coming from? Will it be from independent ad tech?
- WPP is reported to have taken the stance that it will no longer share media data with consultancy Accenture, given its role of acting as both an auditor and a media agency. Details are as yet unclear, but lots of questions arise from this as to the future of the service layer.
