On Tuesday, the U.S. Department of justice and 11 states announced antitrust lawsuits against Google, the most significant antitrust action since Washington fought Microsoft more than 20 years ago. But experts warned that those hoping for a major change in the technology industry could be disappointed, and the lawsuit is unlikely to shake Google’s dominance. Antitrust experts believe that the coming antitrust action is more like a tremor than a major earthquake in the field of science and technology. Even if the U.S. Department of justice tries and wins the case, Google’s role in people’s lives is likely to change gradually, and it may take years to complete. Eleanor fox, a professor of trade regulation at New York University Law School, said: “people should not see this as” the beginning of Google’s Doomsday. “Many people don’t necessarily question Google’s problems because of this antitrust lawsuit.” For many years, critics have argued that big technology companies such as Google, Amazon and Facebook have too much power and often abuse their dominant market position. But historically, government efforts to contain powerful technology companies have been highly challenging. In Europe, regulators have filed three different antitrust actions against Google in the past 10 years and imposed fines of up to $9.46 billion in response to complaints about Google’s price comparison service, Android mobile operating system and Adsense platform. Christian Bergqvist, a law professor at the University of Copenhagen in Denmark, said the US antitrust action showed that the US government had adopted a European style approach of skepticism towards technology giants, but it could be too late. “We are converging in a very positive way to some extent,” he admits Nevertheless, he believes that Europe’s actions provide a warning lesson for US antitrust enforcement. < / P > < p > in a study published last month, an academic advising Google’s European rivals said the company’s price comparison service was still flouting EU rules. Google denied the charge. However, it is obvious that the huge fine for many years has limited impact on the European market. Google’s Chrome browser has a larger market share in Europe than in the United States, and Android still dominates. The antitrust litigation against large technology companies in the United States has also had mixed results. Microsoft basically won a battle with the government in the 1990s, but many industry analysts believe that the company’s troubles in the early 21st century are largely due to the pressure of the antitrust case. Similarly, the government eventually quashed the antitrust suit against IBM in the 1980s, despite the company’s subsequent difficulties. The spin off of at & T in 1984 is a good example. This case led to a large-scale restructuring of the U.S. telecommunications business, which had a wide impact on consumers and enterprises. Many critics believe that the “fine forget” approach to regulation of large technology companies is a failure, and they are pushing for more solutions like at & T splitting. “Nothing is impossible,” said Ryan shores, a U.S. Justice Department official, when asked on a conference call on Tuesday about specific actions to be taken. But legal observers are skeptical about whether government lawyers will push for a spin off. Bergquist said Google’s services were organized into a series of loss making “moats” to protect its “cash cow” (advertising). Even if some of these moats are acquired by competitors or transformed into independent enterprises, it is difficult to see how they can survive on their own. < / P > < p > experts believe that even if Google is not actively split up, the government’s victory or settlement is likely to change the way Google works, but the impact may be very limited. “Google may be affected by this, but its market position in many areas is unlikely to change substantially,” said Jonathan Rubin, who specializes in antitrust law Chinese version of K-car: reading a10e design drawing exposure
