“A US judge has ruled tech giant Google has a monopoly in online advertising technology.

The US Department of Justice, along with 17 US states, sued Google, arguing the tech giant was illegally dominating the technology which determines which adverts should be placed online and where.

This is the second antitrust case Google has lost in a year, after it was ruled the company also had a monopoly on online search.”


“The US case will now move to a second “remedies” phase, which could also lead to Alphabet being broken up, said John Kwoka, a professor of economics at Northeastern University.”
