Public opinion has long been recognized as the cornerstone of democratic life, guiding governance, shaping policy, and reflecting societal values. Classical theorists such as Walter Lippmann, John Dewey, and Jürgen Habermas debated its nature and role, with emphasis on media, deliberation, and collective reasoning. In the contemporary era, however, the rise of digital platforms has transformed the ways in which public opinion is expressed, contested, and mobilized. This paper investigates the formation of public opinion in the digital age through a mixed-method research design that integrates qualitative content analysis, sentiment mining of social media, comparative surveys, and expert interviews. Case studies of elections, pandemic responses, and online movements both global and Indian (such as the #FarmersProtest and #MeTooIndia) highlight how platforms like X (Twitter), Facebook, and WhatsApp simultaneously expand inclusivity while intensifying risks of polarization and misinformation.The findings reveal that while digital platforms accelerate participation and amplify marginalized voices, they also compress deliberation time, foster echo chambers, and undermine trust through viral misinformation. Algorithms play a central role in shaping exposure and engagement, creating both opportunities for democratic mobilization and challenges to information integrity. In the Indian context, social media has become a powerful arena for electoral campaigning, civic activism, and grassroots movements, yet also a space of digital manipulation. The study concludes that the digital public sphere is both transformative and disruptive. Harnessing its democratic potential requires fostering digital literacy, ensuring transparency in algorithmic governance, and cultivating responsible digital citizenship to preserve the resilience of democracy.
