Cookiepocalypse refers to the phasing out of third-party cookies in Google Chrome by 2022 in order to increase user privacy, which is the final straw in the continuous decline of the third-party cookie. This fundamentally changes the way advertisers and web page owners can use cookies and collect data from visitors, and how they can advertise to users.
Google said in a January 2020 blog that it intends to use a set of open standards to sustain “a healthy, ad-supported web in a way that will render third-party cookies obsolete” through its Private Sandbox initiative.
Google Chrome is the most widely used browser worldwide, with over 60% of users depending on it for their everyday browsing and web page access, meaning that users impacted by the cookiepocalypse represents a significant part of the world wide internet user market.
