Ad cookies facing the crunch

Episode Summary

Executive Summary: This Tech Tent episode examines the upheaval in online advertising as Apple and Google clamp down on user tracking. Changes like Apple's opt-in prompt and Google's cookie phase-out threaten targeted ads, impacting businesses and free internet services. The program explores industry reactions, including workarounds like fingerprinting, and debates whether privacy benefits outweigh economic consequences. It highlights a contrarian view that targeted ads reduce inequality by funding free services globally.

Main Topics: Apple's Privacy Move (Priority: 5/5): Apple will require apps to ask users to opt in to tracking via a pop-up, with early surveys suggesting about 80% will refuse. This threatens ad revenues for companies like Facebook. Google's Cookie Phase-Out (Priority: 5/5): Google plans to stop supporting third-party cookies in Chrome and is trialing a replacement called FLoC (Federated Learning Cohorts), which groups users by interests without identifying individuals. Industry Workarounds (Priority: 4/5): Advertisers are exploring alternatives like fingerprinting (combining device characteristics) and new identifiers, despite Apple's resistance. Chinese advertisers are testing their own systems. Economic Impact and Inequalities (Priority: 4/5): Targeted advertising funds free services globally, creating a redistribution of value from affluent users in the global north to less advantaged users in the global south (e.g., $25 billion/year via Facebook). Contextual Advertising Revival (Priority: 3/5): Advertisers may revert to targeting based on content context (e.g., holiday ads on travel sites) rather than personal tracking, a method similar to pre-digital practices. Criticism of YouTube Kids (Priority: 2/5): US politicians labeled YouTube Kids a 'wasteland of vapid consumerist content,' with over 95% of videos having low educational value, raising concerns about hidden marketing to children.

Key Arguments: Privacy-focused changes by Apple and Google threaten the free internet model funded by targeted advertising. Targeted ads reduce inequality by enabling small businesses to advertise and by redistributing revenue from wealthy users to less affluent regions. Industry workarounds like fingerprinting may undermine privacy goals, but Apple claims it will not allow them. Contextual advertising, based on content rather than user behavior, offers a viable alternative to tracking. Losing targeted ads will hit small publishers hardest, potentially leading to paywalls or subscription fees for previously free apps. The debate involves competing interests: Apple uses privacy as a marketing differentiator, while Google may concentrate its ad dominance through new systems like FLoC.

Data Points: User opt-out rate: 80% - Early surveys suggest 80% of users will refuse tracking when presented with Apple's privacy pop-up. Facebook advertisers: 7 million - Number of different advertisers on Facebook, highlighting accessibility for small businesses. Google advertisers: 4 million - Number of different advertisers on Google, underscoring the scale of targeted advertising. Revenue per user by region: $120-130 vs. under $10 - Facebook's annual revenue per user in North America/Europe compared to 'rest of world' region (Africa, Latin America, parts of Asia). Global redistribution value: $25 billion - Annual value redistribution from global north users to global south users via Facebook's advertising model. Kantar's panel size: 25 million - Number of consumers worldwide who have opted into Kantar's survey panels for ad measurement. Digital campaigns measured by Kantar: 25,000 - Number of digital campaigns measured to date via privacy-compliant integrations.

Pivotal Quotes: "The app that you loved using for free might suddenly ask you to log in or even pay for it." — Lara O'Reilly (Insider): Discussing potential consequences of Apple's privacy changes for users of free apps. "Targeted digital advertising is a lot more accessible to small businesses and to local businesses than traditional forms of advertising." — Sam Gilbert (researcher and author): Arguing that targeted ads lower barriers to entry for smaller advertisers. "It funds the provision of universal free services to everybody in the world who has got a device and has got an internet connection." — Sam Gilbert: Explaining the redistributive function of online advertising, especially for users in the global south.

Implications: The impending changes will reshape how advertisers target users, potentially reducing free services and increasing reliance on subscription models. Privacy gains may come at the cost of reduced economic opportunities for small businesses and less access for underprivileged users. The industry faces a rocky transition with workarounds like fingerprinting and renewed focus on contextual ads.
