Back in May, we looked at a Google proposal
to replace third-party
cookies with something called the
“Federated Learning of Cohorts”
(FLoC). Third-party cookies were once used to track users all over the web
so that advertisers could, supposedly, target their ads better, but, of the
major browsers, only Google’s Chrome browser fails to block them today. Google
took a fair amount of flak for FLoC, since it was not perceived to be much
of a win for users’ privacy—and was mostly a sop to the (Google-dominated)
web-advertising industry. Now the company is back with a different
proposal that could, eventually, replace third-party cookies in Chrome: Topics.
