EU proposes breaking up Google's ad business over anti-competitive practices.

The European Commission has issued a statement of objections to Google, threatening the company with its harshest regulatory penalty to date, which could include selling part of its adtech business to address concerns about anti-competitive practices. The adtech business accounted for 79% of Google's total revenue last year. The EU antitrust chief said a behavioural remedy is unlikely to be effective at stopping the anti-competitive practices. Google disagreed with the Commission's charge. The Commission said Google favours its own online display advertising technology services to the detriment of competing providers of advertising technology services, advertisers and online publishers.
