Google is facing a life and death test? The entire Silicon Valley is watching this epic lawsuit. A month ago, a US district judge announced that Google's search engine violated monopoly laws, but has not yet decided on the punishment to be imposed on Google and its parent company Alphabet. What is even more breathtaking for the industry is that on Monday, the case of the US Department of Justice suing Google for illegally monopolizing the digital advertising industry will also enter trial. This is Google's second key antitrust case, which could also become a life and death test for the company, and even be jokingly referred to as the "bankruptcy battle" by some people.
