Abstract

This research explores the transformative role of digital communities on social media platforms in shaping personal identities, consumer behavior, and professional aspirations. By examining the interplay between these communities, brands, and individual users, the research highlights the evolving nature of online interactions and their broader societal impacts. The research employs Media Ecology Theory, Social Capital Theory, and Self-Determination Theory to understand these dynamics. A quantitative survey targeting young adults in Karachi provides insights into the extent and nature of community influence on daily life. Findings reveal significant impacts on cultural perceptions, career goals, and mental well-being, emphasizing the need for authenticity and ethical engagement in digital spaces. Future research directions include longitudinal studies and cross-cultural comparisons.
