This study explores the astonishing global success of the Silicon Valley and investigates the unique history, rise and the major technological accomplishments of the region. The Valley has unique features and key elements that turned it into the most focal point of the modern digital age. Therefore, it is critical to first gain an in-depth understanding of its history, distinctive ecosystem and the advantages that developed the region into its current form. The book then focuses on the founding, success and global impact of modern Silicon Valley technology companies that are prime examples of disruptive forces. However, while Big Tech has delivered revolutionary innovations and capabilities, the Valley is currently facing a number of social, environmental and economic challenges, which are also examined. Thus, the last part of the study investigates the challenges and potential dangers emanating from the tech giants' success and explores if they have become too big to be controlled.
