Google plans to stop selling ads based on individuals’ browsing across multiple websites, a change that could accelerate disruption in the digital advertising industry. The Alphabet Inc. company said on Wednesday that it plans next year to stop using or investing in monitoring technologies that uniquely identify web users as they move from site to site across the internet. The decision, coming from the world’s largest digital advertising company, could help push the industry away from the use of such individualized tracking, which has come under increasing criticism from privacy advocates and faces scrutiny from regulators.Google’s heft means the change could reshape the digital ad business, where multiple companies rely on tracking individuals to target their ads, measure the ads’ effectiveness and stop fraud. Google accounted for 52% of last year’s global digital ad spending of $292 billion, according to Jounce Media, a digital ad consultancy.
