In today’s digital era, Online Social Networks (OSNs) have emerged as powerful platforms that shape the way we connect, communicate, and share information. Among these platforms, Instagram stands out as a prominent player, attracting billions of users worldwide and becoming a significant cultural phenomenon. With its visually appealing content and global reach, Instagram has redefined the landscape of social media, transcending geographical boundaries and bridging diverse communities. The objective of this thesis is to analyze and study the effects of Instagram usage on the homogenization or preservation of geographical and cultural identities. The proposed approach involves the analysis of Instagram profiles from five different European countries: Italy, France, Germany, the United Kingdom, and Spain, across three distinct social macro-areas, namely politics, culture (specifically athletes, models, and actors), and academia (university profiles).
