Google’s move to drop cookies pushes advertising into new era
Google is upending the advertising world with its decision to “render obsolete” a key tool used by marketers for years to track would-be customers as they move around the Web: it’s phasing out the cookie. On Tuesday, the company said it would stop supporting third-party cookies over the next two years. Cookies the bits of code that lodge in people’s browsers and follow them around the web allow advertisers to target people with ads for websites they previously visited, and keep track of which ads finally induced a purchase.
