Goal: Previous studies have shown that an ecosystem of collaboration among diverse organisations is more useful for the development and application of artificial intelligence than a single organisation working on its own. It has also been pointed out that, particularly in the case of generative AI, which has become popular in recent years, companies such as Big Tech play a significant role in shaping and developing ecosystems. This study aims to quantitatively analyse the network structure of cooperation relationships among organisations in generative AI and to demonstrate the characteristics of big techs' positioning in this network structure compared with other organisations. Methodology: As an analysis method, information from recent newspaper articles was analysed using social network analysis to examine the current situation. Conclusion: The analysis revealed several characteristics of Big Tech's network structure. As a future task, the information that cannot be obtained from newspaper articles alone should be supplemented by other research methods.
