"Google Disables Third-Party Cookies in Chrome, Impacting 30M Users and Shifting Ad Strategies"

Google is initiating a significant privacy update by automatically blocking third-party cookies for 30 million Chrome users, which is about 1% of its user base, starting January 4. This move is part of a broader plan to eliminate cookies entirely by the end of 2024. To balance user privacy with its advertising business, Google is introducing 'Tracking Protection' to prevent cross-site tracking and 'Ad Topics' to deliver relevant ads based on users' browsing topics, rather than using cookies to track individual browsing data.
