Alphabet Inc's Google upended plans by European media companies to block it from harvesting data about their readers and slash some of its dominance in online advertising, seven people involved in the talks said this month.
Publishers had expected to use data privacy measures going into effect Aug. 15 to bar Google from storing insights about readers, sapping the data advantage that has enabled it to dominate a market filled with advertisers hungry for information to target potential customers.
But Google said it will cut off publishers from a lucrative flow of ads if they follow through with curbing its data collection. Negotiations continue, but Google holds greater leverage because it dominates in both advertising tools and access to advertisers within the $100 billion annual global banner ads market.
