Next year, Alphabet Inc's Google plans to phase out technology in its Chrome browser that lets other companies track users' web browsing. But privacy activists say companies that develop online ad technology abuse cookies by tracking users across many websites and letting brands use the data to target ads. Brands could target their ads to a cluster interested in buying a car, for example, rather than relying on cookies that have tracked specific users across car-buying websites. It is also possible that showing someone ads based on activities they undertook on another website will grow unpopular. Before cookies led to advances in targeting, ads more commonly were related to surrounding content, so a video about vaccines would feature ads from medical fields.
