I don't recall the first date for Googles set for the demise of the cookie. I think the second deadline was extended t the back half of 2022. Just yesterday, 7/27/22, I learned Google was delaying the demise of cookies even further. It now looks like it will be the back half of 2024.
This makes me and many digital marketers quite happy. Cookies while not perfect help fuel the growth of the Internet.
Marketers rely on cookies, some may over-rely on them, they are important to make sure consumers see the ads they are most interested in and marketers are able to serve ads to the most likely audiences.
Long live the cookie.
