The Mighty Third Party Cookie

A day without third-party cookies is looming: By late 2023, Google plans to eliminate the use of third-party cookies in Chrome—a browser used by an estimated 3.04 billion people worldwide, essentially disabling how most of our advertising and technologies work today.

Third-party cookies have been the backbone of the marketing industry for the past decade. They allow ad platforms to trace individual users across the Web, understand users' habits and interests, and then serve ad content that is relevant to each user's browsing history.
