It is reported that the competition and market authority (CMA), the UK antitrust regulator, today launched its second antitrust investigation into Google's advertising business, saying that Google may distort competition and illegally favor its own services. Earlier this year, CMA has launched an investigation into an online display advertising service transaction previously concluded between Google and Facebook parent company meta.
As early as 2018, Google and Facebook reached an online advertising deal codenamed Jedi blue.
It is said that this is a "cooperation and mutual assistance" agreement signed by Google and Facebook. Under the agreement, the two companies maintain a "tacit understanding" in some areas, such as the online advertising market, in order to stifle an advertising tool. The tool is increasingly popular among publishers and is supported by Facebook.
At present, governments all over the world are strengthening the supervision of American technology giants and conducting a number of investigations on their market position. Last year, CMA also created a special digital market department to prevent Google and Facebook from using their dominant position to crowd out small companies and put users at a disadvantage.
